Hi, I recently switch from portainer to komodo and I don't look back at all so far. The only "feature" I could not fully replicate compared to portainer is the webhook redeployment of stacks. Portainer had a webhook that does not need a payload, komodo on the other hand does. The problem I ran into, is the release event gitlab provides. The others I tested (push and deployment) work just fine, but the release event throws the following error when I check the komodo logs:

2025-06-02T11:12:06.982892Z  WARN StackWebhook{id="some-service"}: core::listener::router: Failed at running webhook for stack some-service | Failed to parse gitlab request body: missing field `ref` at line 1 column 1992

tag even error see below

I could not find any info on what komodo actually needs inside the payload to manually send a request to komodo and skip the whole gitlab webhook part.

Either way, this Issue has two parts:

Release&Tag webhook events from gitlab do not work
Does the webhook call to komodo actually need the info from the payload and/or would it be possible to have a (separate?) webhook that is callable w/o a payload?

EDIT: Why I am not using other webhook events?

Push: The pipeline needs to build the new image first, so push cannot work
Deployment: Does technically work, but it triggers twice. Once when the deployment job starts and once when it ends. Two webhook calls are unnecessary. This is my current workaround
Tag: Fails with a different error request branch does not match expected
Pipeline: Trigger gods knows how often, even worse than deployment
Everything else does not fit my use case of redeploying a stack in the last pipeline job

My preferred solution would be the release event, but a payload-less webhook as portainer has it would also be an option, albeit probably more work on your end.

EDIT2:
My newest workaround is more like an alternative solution by adding another ci job that calls the komodo api directly with DeployStack Link and forcing a pull&deploy of the whole stack. It does need an additional ci job and eliminates the need for the webhook alltogether, but the problem with webhook itself still persists. So I do have something that does works for me now, but I will keep the issue open nontheless, for everyone else who expects the (gitlab) webhook to work with these events (release/tag and maybe others, i did not test all of them).

If you are still having this issue, double check and make sure your webhook is setup with content-type application/json. The default application/x-www-form-urlencoded will throw this same error.

Even with content-type set to application/json I still get Failed to parse github request body: missing field ref at line 1 column 9615 in komodo's logs
