Permission issue Graphs API - Unable to update/read permission

Question

My goal is to make a simple website that reads my Microsoft To-Do list.

I've made an app in Azure, added a few permissions to test with and made the connection in my website.
Connection is ok with personal authentication, but I keep getting this error message;

{"error":{"code":"UnknownError","message":"","innerError":{"date":"2022-07-21T20:46:40","request-id":"**","client-request-id":""}}}  

I have removed both IDs for privacy reasons.

Now I have noticed I get this same error when I try the same endpoint in the Graph Explorer, without setting permissions. After specifically consenting these permissions in the Graph Explorer, I get the proper result.

I tried adding, removing, granting admin, multiple permissions but with no result. While doing this I added another issue; whenever the website asks log-in through the oAuth, it asks way too many permission then configured in the app. I searched everywhere through Azure to remove them, but again without result. (Also tried removing them with Powershell, no result)

If more information is needed, please ask.

Answer 1

Hi @MB , I tested it locally using the postman tool and it worked. When authenticating using the authorization code grant flow, you can change '{tenant}' to 'common' or 'consumers' so that personal account authentication can be used, and don't forget to add tasks.readwrite to scope.

At the same time it will return a similar M.R3_BAY... the code that finally got something like EwB4A8... Token, hope to help you.
