AADSTS500011
InvalidResourceServicePrincipalNotFound
What it means
The resource the app asked for wasn't found in the tenant.
How to fix it
Check the resource or scope URI, and that the resource app is installed and consented in this tenant.
How to investigate
- Compare what the app sends (client ID, redirect URI, scopes, tenant) with the app registration.
- Decode the token or request: the JWT and SAML decoders on this site show exactly what was sent.
- Check the app's credentials (secrets and certificates) and whether the service principal exists and is enabled in this tenant.
- Search the sign-in logs for the request ID or correlation ID from the troubleshooting details on the error page.
