Real-Time Logs not showing error responses

I'm trying to debug an issue with some sporadic errors which result in a 401 api response from my pages function. When using the Real-Time Logs stream, all 200 OK responses come through but the 401 error responses do not. How can I get all api responses to show? Would it be framework specific? I'm using Nuxt3 and have logging on all requests, responses and errors through Nitro hooks api.

export default defineNitroPlugin((nitroApp) => {
  nitroApp.hooks.hook('request', (event) => {
    console.log('Request', event.method, event.path);
  });

  nitroApp.hooks.hook('beforeResponse', (event, { body }) => {
    console.log('Response', event.method, event.path, { body });
  });

  nitroApp.hooks.hook('error', (error, { event }) => {
    console.error(
      `${event?.path || 'Undefined Server Event'} Application error:`,
      error,
    );
  });
});

export default defineNitroPlugin((nitroApp) => {
  nitroApp.hooks.hook('request', (event) => {
    console.log('Request', event.method, event.path);
  });

  nitroApp.hooks.hook('beforeResponse', (event, { body }) => {
    console.log('Response', event.method, event.path, { body });
  });

  nitroApp.hooks.hook('error', (error, { event }) => {
    console.error(
      `${event?.path || 'Undefined Server Event'} Application error:`,
      error,
    );
  });
});

realtime logs has all requests

But I for certain don't see the logs for the error responses. Didn't apply any filters either

From devtools the error comes from id z4y4l3.... but it's not the CF log stream

AGillOP•2mo ago

can ignore the "refresh_token" calls, more focused devtools pic

what's the body on the 401?

AGillOP•2mo ago

{
  "url": "/api/reports/z4y4l3jpgmyq0luxgi9s1zuy?items=slim",
  "statusCode": 401,
  "statusMessage": "",
  "message": "signature verification failed",
  "stack": ""
}

{
  "url": "/api/reports/z4y4l3jpgmyq0luxgi9s1zuy?items=slim",
  "statusCode": 401,
  "statusMessage": "",
  "message": "signature verification failed",
  "stack": ""
}

That's the error I'm trying to debug, which happens periodically

yeah not seeing either the tabler.json or the z4y request, wonder if too many events in short time? not fully sure

AGillOP•2mo ago

Heyy ok cool ~~ looks like the log just came in. But 10 minutes after:

AGillOP•2mo ago

10:04 -> 10:14 ^ don't know why I got lucky with that request. the issue still persists. not seeing logs for the error responses. even after waiting

AGillOP•2mo ago

I thought this was kinda fun. I was debugging the problem and waiting for an error log. And I noticed a bot spamming my app 😆

AGillOP•2mo ago

Any ideas Walshy? Outside of that one odd time where I was lucky and got the error log 10 mins later. I can't see any error responses in the real time logs stream. Even after waiting. Hm OK maybe something fishy is going on. I deployed a change to throw some dummy errors and they should up in the log stream as expected. But this random 401 error is also not being caught in my global try catch I set up... so with that behaviour plus the log not showing up in the stream... makes me wonder if the request isn't being sent to my server at all? In other words, is the request being routed to another server? Like a MITM attack? 😬 Well I called someone who's a few cities away and they also get the same behaviour as me. So relieved to know it's not someone hijacking my network To close this thread. It looks like the intermittent errors have stopped. Don't know the cause maybe a hiccup in worker runtime.
