Describe the problem/error/question
I have a workflow that is called via a webhook with the goal of returning a specific file. Until now, I used the webhook node with the parameter ‘response data’ set to ‘first entry binary,’ and it was working perfectly.
However, I believe that since an update, this functionality is no longer working. n8n returns a large JSON response like this:
So, I tried using the ‘respond to webhook’ node. I conducted several tests, and my workflow works when the size of the returned file is up to 20MB. However, with a 23MB file, I do not receive the file, and my request is pending indefinitely.
The strange thing is that my workflow works when I use the webhook test; the file is returned properly, but it does not work in production. In execution tab, the workflow ended normally but I never received a file.
For info, I set the ENV var N8N_PAYLOAD_SIZE_MAX to 500 in n8n_main, workers and webhook instances.
What is the error message (if any)?
No error, the workflow show a successful execution :
