Problem Description

Hey there! I'm facing these error when trying to update stack via webhook. But when I'm manually redeploying it stack will deploy without error.

{"level":"info","repository":"https://github.com/qrvers/burn_tobacco/","composePath":["docker-compose.yml"],"destination":"/mnt/portainer-compose-unpacker","env":[],"skipTLSVerify":true,"time":1718806524,"caller":"/home/runner/work/compose-unpacker/compose-unpacker/deploy.go:31","message":"Deploying Compose stack from Git repository"}

stack deployment failure
{"level":"error","error":"authentication required","time":1718806524,"caller":"/home/runner/work/compose-unpacker/compose-unpacker/deploy.go:104","message":"Failed to clone Git repository"}

What may gone wrong? My fine grained personal access token is valid for authentication yet still facing this error

This started happening when I created a stack that uses relative path at /mnt
When redeploying by hand it works like a clock but once I make POST request to webhook url https://portainer.XXXX/api/stacks/webhooks/XXXX it gives me this error

{
    "message": "Failed to update the stack",
    "details": "failed to deploy a docker compose stack 31: an error occurred while running unpacker container with exit code 255: authentication required"
}

I am also using an additional (self-hosted) registry but it doesn't require authentication

Expected Behavior

For the stack to deploy

Actual Behavior

compose-unpackerer throws error stack deployment failure with following logs

{"level":"info","directory":"/mnt/portainer-compose-unpacker","time":1718806524,"caller":"/home/runner/work/compose-unpacker/compose-unpacker/deploy.go:57","message":"Checking the file system..."}
{"level":"info","directory":"/mnt/portainer-compose-unpacker/stacks/burntobacco-dev","time":1718806524,"caller":"/home/runner/work/compose-unpacker/compose-unpacker/deploy.go:83","message":"Creating target destination directory on disk"}
{"level":"info","repository":"https://github.com/qrvers/burn_tobacco/","path":"/mnt/portainer-compose-unpacker/stacks/burntobacco-dev","url":"https://github.com/qrvers/burn_tobacco/","depth":1,"time":1718806524,"caller":"/home/runner/work/compose-unpacker/compose-unpacker/deploy.go:98","message":"Cloning git repository"}
stack deployment failure
{"level":"error","error":"authentication required","time":1718806524,"caller":"/home/runner/work/compose-unpacker/compose-unpacker/deploy.go:104","message":"Failed to clone Git repository"}

Steps to Reproduce

1 Create custom registry and push at least one image
2 make a docker-compose use that image
3 create stack that has relative path at /mnt so it looks like /mnt/portainer-compose-unpacker/stacks//
4. send POST to https://portainer./api/stacks/webhooks/XXXX
