Homebridge FetchError and Socket Hang-Ups with Feller-Wiser Plugin on Raspberry Pi #20

Open Villagio88 opened 1 month ago

Villagio88 commented 1 month ago

Describe The Bug: I am experiencing frequent issues with Homebridge on my Raspberry Pi where I receive HTML instead of JSON responses from API calls, causing the server to crash and preventing scenes from executing properly. There are also frequent socket hang-ups.

To Reproduce:

  1. Start Homebridge with the feller-wiser plugin enabled.
  2. Attempt to control any accessory or trigger any scene.
  3. Observe the error in the Homebridge logs indicating JSON parsing errors and socket hang-ups.

Expected behavior: I expect that API calls should return valid JSON responses and not cause the server to hang or crash. The scenes and accessories should operate smoothly without any interruptions.

Dear @Villagio88, thanks for reporting this.

Can you ensure, that your accessToken you provided in Config is a valid one? The implementation mainly is mainly following the "happy path" so the json-parsing expects (unchecked) json. Most likely html is return in cases where you're not authenticated.

Thank you in advance.

Thank you for your swift response!

I can confirm that the accessToken provided in the config is valid. Operating individual switches works perfectly; however, when executing scenes, only about half of the actions complete successfully, and then I encounter the errors mentioned previously. This suggests that the issue occurs more frequently when there are multiple simultaneous requests.

Could there be an issue with how the plugin handles multiple simultaneous API calls during scene execution? Maybe it doesn't manage concurrent requests effectively, leading to these errors and partial scene execution.

Below, I have attached a log showing various errors that occur during these operations. You'll notice multiple "socket hang up" errors and "invalid JSON" responses, which seem to happen under the load of multiple requests. These details might help in identifying whether the issue is related to handling simultaneous API calls.

Thanks again for looking into this.
