Report ID not found in the Workspace

Hi,

I am trying to embed a Power BI Report to a Web App. I am using the Sample Web App provided in the Github and the sample report. I am following the steps mentioned in the link https://docs.microsoft.com/en-us/power-bi/developer/embed-sample-for-your-organization#embed-your-content-using-the-sample-application

However, I am still getting an error on running the application.

Error: "Report with ID: '26209ae2-8cd8-4ae4-8760-41aa589449ec' not found in the workspace with ID: 'fa957a68-fd4d-463f-9cd6-20003c3fe153', Please check the report ID. "

As per my knowledge I am giving the right id for both in the config file.

Can anyone help me identify if I am missing something here?

Thanks!
