argument list too long

[davama]

Hello,

We have a simple hook that accepts the headers and payload as arguments for the script:

    {
        "id": "microservice",
        "execute-command": "script.py",
        "command-working-directory": "/etc/webhook",
        "include-command-output-in-response": true,
        "pass-arguments-to-command": [
            {
                "source": "entire-headers"
            },
            {
                "source": "entire-payload"
            }
        ]
    }

We are trying to send a payload with thousands of keys, but webhook gives this error:

[webhook] 2023/01/19 15:09:55 [94fef6] error occurred: fork/exec /etc/webhook/script.py: argument list too long

Looking around I found this issue/comment which mentioned the stream output approach.

There is also this PR which implements this stream option.

So I simply wanted to make sure, is the PR and the issue option the same solution?
And would it help me to solve my issue?

Any input is appreciated

Best,
Dave

Playing around, i figured out how to use a hook with encoded data:

Added this hook as a workaround.

argument list too long is a linux limitation (if my memory serves me right)

Dont see a solution for this.
