The error message "Your client app is not configured with the appropriate oauth1 app permissions for this endpoint" suggests that your Twitter app does not have the necessary permissions to access the specific endpoint you are trying to use.
To resolve this issue, you need to make sure that your Twitter app has been properly configured with the necessary permissions. Follow these steps:
- Go to the Twitter Developer Portal (https://developer.twitter.com/en/portal/dashboard) and log in with the Twitter account associated with your app.
- Select your app from the dashboard.
- Go to the "Settings" tab for your app.
- Under the "Permissions" section, ensure that the appropriate permissions for your desired endpoint are enabled. For example, if you are trying to access user data, make sure the "Read and Write" permission for "Users" is enabled.
- Save the changes to your app settings.
After making these changes, try accessing the endpoint again. If the issue persists, double-check your code to ensure that you are using the correct authentication method and credentials when making requests to the Twitter API.
