I've created the role, integration and user for an M2M OAuth2 client credentials, generated the public/private keys JWT. however when I use the generate JWT token to connect to a rest endpoint to view customer list for example, I get an INVALID_LOGIN error. Nothing shows up on Login Audit trail. I've checked and confirmed the ClientId, ClientSecret, Certifcateid, etc. baseUrl is https://<sandbox>.suitetalk.api.netsuite.com/services/rest/record/v1 - JWT token is generated correctly according to https://blogs.oracle.com/developers/post/using-sa-connect-with-oauth2. what else am i missing?

AI generated answer (using internal Slack threads):

Based on the conversations, there are a few things you could check: 1. Make sure the account ID is in all caps. This is a common mistake that can lead to an INVALID_LOGIN error. 2. Ensure that you have added REST Web Services to your role. This is necessary to make REST API calls. 3. Check if you have added authorization data to request headers. This is a common issue that can lead to an INVALID_LOGIN error. 4. If you're using a sandbox, ensure that you haven't mixed up _ and - in the realm. 5. Check the Login Audit Trail for more details about the error. If you're seeing an "EntityOrRoleDisabled" error, it means that the entity or role you're trying to use is disabled. Remember to double-check all your credentials and settings. If you're still having issues, you might need to revisit the setup steps. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
