Hi @Ranjeet Pawar ,

Thank you for the detailed description of the case.

When I received the case, I searched a lot of documents did a lot of researches. And I feel regretful to inform you that no documentation has been found can resolve this error now.

As a workaround, I recommend you try to use Postman and check if can get the "Access_token". Then get the file from SharePoint using Rest API;

Steps:

1. Follow the steps in the documentation to get the "Access_token" (as shown in the following screenshot).
