解决IDEA Key is invalid.问题

The error message "The specified 'scope' is invalid" usually occurs when the requested scope is not valid or does not exist in the authorization server.

To resolve this error, you can try the following steps:

1. Double-check the scope parameter in your authorization request and ensure that it matches the defined scopes in the authorization server.

2. Check if the requested scope is supported by the authorization server, as some servers might have limited scopes available.

3. If you are using a third-party library or SDK to make the authorization request, make sure that it is configured correctly and is sending the correct scope parameter.

4. If none of the above steps work, you may need to contact the authorization server administrator or consult their documentation for more information on supported scopes.
