Webhook is not working

[bgfborges]

I'm using the fal-ai/flux-lora-fast-training model. And I'm passing the webhook correctly (as well as my app is receiving the requests – POST) in the passed Endpoint. But I don't receive back.

NOTE: I suspected it could be an ngrok problem, but everything indicates me the requests are being received into my application (I made many tests with different proxies, and ngrok is passing the requests – and I was not able to see through the logs if it tried and failed to POSt it to my app).

Well, I don't know exactly who I should contact in order to request a feedback on why it's not posting the websocket, the model? Here? Where?

The testing input received by Fal:

{
  "images_data_url": "https://pub-e90f31e237bc40d8acbe5f40adfgt56c365.r2.dev/lora-682f9b25b69bf20c7aeb205b/lora-682f9b22b69bf20c7aeb2057.zip",

  "trigger_word": "682f9b22b69bf20c456b2057",
  "webhookUrl": "https://conversely-evolving.ngrok-free.app/imagine/fal/webhook"
}

Output:

can you share how you actually set the input in the function call?

Hey @bgfborges

The webhookUrl is not passed as part of the input, but as its own property. You can see an example here: https://docs.fal.ai/model-apis/clients/javascript#2-queue-management

Let me know if that works or this is still a problem.
