external backend did not receive any request

Hi @BlueStone. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information in the provided knowledge sources, there is no explicit documentation or issue directly describing the "500 OK" error when using routeRules to proxy to an external backend, especially in the scenario where the external backend did not receive any request. However, here are some relevant points and possible directions based on the sources: - Nuxt's routeRules can be used to proxy requests to an external backend, for example:

  routeRules: {
    '/backend/**': {
      proxy: {
        to: `${process.env.NUXT_BACKEND_URL}/**`,
        headers: { accept: 'application/json' }
      }
    },
  }

  routeRules: {
    '/backend/**': {
      proxy: {
        to: `${process.env.NUXT_BACKEND_URL}/**`,
        headers: { accept: 'application/json' }
      }
    },
  }

This is mentioned in a GitHub issue, but there is no further detail about error handling or debugging proxy failures in the sources provided. The user in that issue was asking about TypeScript types, not about proxy errors or 500 responses specifically. There is no mention of a "500 OK" error or the backend not receiving requests in that context. GitHub Issue #31664 - The Nuxt documentation on routeRules and Nitro does not provide troubleshooting steps for proxy errors or explain what might cause a 500 error with an "OK" status message when the backend is not hit. It does mention that routeRules are experimental and subject to change, which could mean there are edge cases or bugs, but no specifics are given about this error. Nuxt Docs: routeRules, Nuxt Docs: Server - There is no information in the sources about debugging or logging proxy requests made via routeRules, nor about how to determine why a request might not reach the external backend. Summary:
I'm sorry, but the knowledge sources do not contain enough information to explain the cause of a "500 OK" error when using routeRules to proxy to an external backend, especially when the backend does not receive the request. You may want to check for updates in the Nuxt or Nitro issue trackers, or enable additional logging to debug the proxy behavior. If this is a bug, reporting it with a minimal reproduction in the Nuxt repository may help get more targeted support. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
