PBI Custom Connector w OAuth2 grant_type client_credentials fails to refresh data

June 18, 2019, 2:45 pm
$
0
0

Hi,

We have built a Custom Connector using Power Query SDK the to be able to use a vendor system as a data source in Power BI.

We need this because the REST API from the system uses OAuth V2 with the Grant type “Client Credentials”

 

Here’s where our implementation differs from all the examples found online, where all OAuth examples use the Grant type “Authorization code”

 

Anyhow, the implementation works using Power BI Desktop locally,and also works online on powerbi.com (through a On-premise Data Gateway) on the first try and the following tries as long as the Access token has not expired.

 

But if you try to refresh either manually or by scheduler an hour after the initial setup, when the Access Token has expired, the online service doesn’t seem to understand that it has expired and requests a new one. Instead it gets an error when trying to connect to the datasource.

 

The error message under “Dataset” in powerbi.com reports the following:

Something went wrong
Invalid connection credentials.

Please try again later or contact support. If you contact support, please provide these details.
Underlying error code: -2147467259 Table: journal.
Underlying error message: The credentials provided cannot be used for the Vendorsystem source. (Source at Vendorsystem .)
DM_ErrorDetailNameCode_UnderlyingHResult: -2147467259
Microsoft.Data.Mashup.CredentialError.DataSourceKind: Vendorsystem
Microsoft.Data.Mashup.CredentialError.DataSourcePath: Vendorsystem
Microsoft.Data.Mashup.CredentialError.Reason: CredentialInvalid
Microsoft.Data.Mashup.MashupSecurityException.DataSources: [{"kind":"Vendorsystem ","path":"Vendorsystem "}]
Microsoft.Data.Mashup.MashupSecurityException.Reason: CredentialInvalid
Cluster URI: WABI-EUROPE-NORTH-B-redirect.analysis.windows.net
Activity ID: 8bf0a164-83f9-4928-9e0c-f493249a6d7b
Request ID: 9960c0f8-540c-437d-87ba-7f7f28d1ef29
Time: 2019-06-16 22:18:09Z

If I at this point once again on powerbi.com go to Settings – Manage Gateways – Edit Credentials – Sign in and changes the name to enable the “Apply” button, it works for another hour.

 

My conclusion is that stated above, that the token acquired gets expired after an hour, but powerbi.com does not try to login again to get a new one.

Troubleshooting this in any deeper extent on my end is hard since most of the requests are made from the cloud service itself.

 

The Vendor System does not implement a "Refresh Token", which is an optional method in the SDK

Extract data from JSON URL

Hi,

 

I'm trying to extract the data from a JSON URL which has only one field like the following:
2019-06-18_15-05-14.png

The integer, in this case 1178, needs to be read from the Advanced Editor in Power BI. It's a variable that keeps changing as more tickets are created. This number needs to be stored and will get used later on in the query.

 

Is there a simple way to achieve this? So far, i've got to:

 	GetEntityCount = () =>
        let Url   = "http://url.freshdesk.com/helpdesk/tickets/summary.json?view_name=all",
            Json  = GetJson(Url),
            EnityCount = ([Json] ("view_count"))
        in  EntityCount

This obviously doesn't work, I've tried multiple things but I can't get it to work.

 

So to be short:
Extract 1 field from a JSON URL / REST API.

Store this field into a variable.

Done.

(Embedded) Slicer target does not match

Just wondering if anyone has hit anything like this before - using PBI embedded, and have a slicer to filter down to specific date ranges (text value, and column is text type).

 

The issue I'm having is I can't set this slicer, at all. Single value slicers work fine, another slicer I have that's multi-select with strings works fine but this one throws out "Filters target doesn't match slicer target."

 

I've attached the filter received from requesting getSlicerState:

getSlicerState.png

 

And here is an example of a filter I sent:

setSlicerState.png

 

 

Going further:

So I was wondering what would happen if I did absolutely nothing and just fed the result of getSlicerState into setSlicerState (without any modifications at all). It throws "slicerTargetDoesNotMatch" - so all evidence is pointing to this not being my issue so far. Sad.

 

 

Any ideas?

I am able to generate the following report.

Project_IDProject_TitleTasks
P-1Project-1Tasks-1
P-1Project-1Tasks-2
P-2Project-2Tasks-3
P-2Project-2Tasks-4

But My requirement is to generate a report like

Project_IDProject_TitleTasks
P-1Project-1

In this case, the Pivoting will not help me. I have alreadty tried.

Qualtrics API/Python Script

I've been trying for the longest to figure out how to import survey results from Qualtrics into Power BI using Python. Qualtrics support has given me code and I was told all I needed to do was change the apiToken, surveyId, fileFormat and dataCenter lines below but I have not been able to get this to work:


# Python 3

 

import requests

import json

import io, os

import sys

import pandas

from pandas.io.json import json_normalize

 

# Setting user Parameters

 

apiToken = '[ID]'

surveyId = "[ID]"

fileFormat = "csv"

dataCenter = ‘[Datacenter]’

 

# Setting static parameters

requestCheckProgress = 0.0

progressStatus = "inProgress"

baseUrl = "https://{0}.qualtrics.com/API/v3/surveys/{1}/export-responses/".format(dataCenter, surveyId)

headers = {

    "content-type": "application/json",

    "x-api-token": apiToken,

    }

 

# Step 1: Creating Data Export

downloadRequestUrl = baseUrl

downloadRequestPayload = {"format": fileFormat, "compress": False, "useLabels": True}

downloadRequestResponse = requests.request("POST", downloadRequestUrl, json=downloadRequestPayload, headers=headers)

progressId = downloadRequestResponse.json()["result"]["progressId"]

print(downloadRequestResponse.text)

 

# Step 2: Checking on Data Export Progress and waiting until export is ready

while progressStatus != "complete" and progressStatus != "failed":

    print ("progressStatus=", progressStatus)

    requestCheckUrl = baseUrl + progressId

    requestCheckResponse = requests.request("GET", requestCheckUrl, headers=headers)

    requestCheckProgress = requestCheckResponse.json()["result"]["percentComplete"]

    print("Download is " + str(requestCheckProgress) + " complete")

    progressStatus = requestCheckResponse.json()["result"]["status"]

 

#step 2.1: Check for error

if progressStatus is "failed":

    raise Exception("export failed")

 

fileId = requestCheckResponse.json()["result"]["fileId"]

 

# Step 3: Downloading file

requestDownloadUrl = baseUrl + fileId + '/file'

requestDownload = requests.request("GET", requestDownloadUrl, headers=headers, stream=True)

 

#data = json.loads(requestDownload.content)

#df = json_normalize(data['responses'])

data = requestDownload.content

df = pandas.read_csv(io.StringIO(data.decode("utf-8")))

df

 

I'm not a developer nor do I have Python experience, so I have no clue what I would need to change to get what I'm looking for. I'm slightly confused because this seems to be code for exporting results to a CSV, but I was hoping to connect straight from Power BI to Qualtrics.

library(sf)
library(rgdal)
library(rgeos)
library(mapview)


setwd("C:/Users/Daniel/Desktop/IDGeo/Earth analytics course_Learn data science/data/week 4")

pivos <- readOGR(dsn = "california/SJER/vector_data",

M2<- mapView(ndwi, alpha.regions = 0.50, na.color = "transparent")
m4 <- mapview(pivos, lwd = 1.5, color = "gray40")

M2 + m4

 

-------------
ndwi = my raster data
pivos = my shapefile

----

In R it works perfectly and returns an interactive map containing my raster data plus myshapefile, however, in pwrbi nothing happen...

Anyone knows what could be happening?
Or, anyone could suggest another way to plot raster + shapefile interactive maps in power BI using R?
Thanks very much, best regards.

Improve Graphic Visualization of 15' auto-refreshing Dashboard

Hi

 

First i ask sorry if my english is bad ora i posted this in a wrong place.

 

i set up a dashboard showed on tvs into my company's office, to inform my colleagues of others desk about daily PnL trend.

I synchronized our SQL Server db to an Azure database and then connected to powerBI through direct query, so i'm able to pin dashboard tiles and auto update this dashboard visualizations while showing them in full screen.

 

All is working fine but the tile's auto formattation is quite ugly and i would like to show on screen better looking visuals, i tried pinning entire page and keep the layout i made on power bi desktop and refresh the page (for the autoupdate) with a chrome's extension that simulate F5 press but in this mode the page get off by fullscreen, so i'm forced to use tile to enable auto data refresh.

 

Is there a method  to improve tile's graphic ? or someone know others workaround that keep the 15' auto refresh?

 

Thank you all,

Angelo.
