I apologize for the inconvenience. In order to fix this issue, you will need to configure the appropriate OAuth 1 app permissions for your client app. This can usually be done by accessing the developer portal or dashboard of the OAuth provider you are using.
Once you have access to the developer portal or dashboard, locate the section for app permissions or scopes. Check if the specific endpoint you are trying to access requires any specific permissions. If yes, make sure you have added those permissions to your client app.
If you are still facing any difficulties or have any specific questions regarding the configuration process, please provide more details about the OAuth provider and the endpoint you are trying to access.
