In Azure cloud, I have created a Function App and added identity provider as Microsoft (Sign in Microsoft and Azure AD identities and call Microsoft APIs). When I tried to access the function app from Android App ( Implemented Auth Using MASL Library), I am getting following error message.
{"code":401,"message":"IDX10511: Signature validation failed. Keys tried: '[PII is hidden]'. \nkid: '[PII is hidden]'. \nExceptions caught:\n '[PII is hidden]'.\ntoken: '[PII is hidden]'."}
How to proceed further? This error information is not enough to debug further.

This needs to be reviewed from the code and configuration. Maybe you are trying to validate the token which is meant for the graph and observing the exception. You can refer to the below similar discussion on the exception :

If it didn't help then I will suggest you to open a
