What is the meaning of the error 'Token type is not allowed' when I try to send a REST API request to SharePoint API from Postman?

The error 'Token type is not allowed' typically occurs when the authentication token you're using to make your REST API request to SharePoint API is not supported or recognized by SharePoint. This can happen if you're using an outdated or incorrect authentication token, or if the token is missing certain permissions required to access the SharePoint API.

To resolve this issue, you should first check that you're using the correct authentication token for your request. You may need to generate a new token or update your existing one. Additionally, make sure that the token has sufficient permissions to access the SharePoint API you're trying to use.

If you're still experiencing issues after checking your authentication token, you should consult the SharePoint API documentation or contact SharePoint support for further assistance.
