Using the Platform UI, my integration fails after the 3600-second token period, returning a 401 error with no valid object. New example:

return z.request(newConfig)
  .then(result => {
    console.info(result.content);
    result.checkStatus();
    const output = result.extractJSON();
    return output;
  })
  .catch(err => ({ userID: 0 }));

I encountered a similar issue while working with token refresh operations. In my case, after some trial and error, I discovered that intermittent backend changes and token schema mismatches were causing the null response. The solution came by adding thorough logging to capture the complete HTTP response before attempting JSON extraction. Additionally, I verified the endpoint configurations to ensure that the expected token object was returned. This methodical approach helped me determine that careful inspection of both frontend request structure and backend response format is essential.

hey, i also ran into this when token refresh failed. my fix was to log the full response and double-check endpoint headers. often a minor misconfig can cause the null output, so make sure every part of the token process lines up
