[Bug]: Calls to /servers/{uuid}/validate do not kickstart validation?

[namgo]

Error Message and Logs

When calling coolify api after successfully creating a server with the api (post, /servers) I am attempting to use either the instant_validate parameter or /servers/{uuid}/validate to validate and install docker engine in place of clicking the "Validate and Install Docker Engine" button.

When using the validate endpoint, I receive a message "Validation started." but there appear to be no deployments queued, nor after roughly 5 minutes has a deployment appeared - coolify hasn't attempted to install docker on the remote host.

When I do click the "Validate and Install Docker Engine" button, validation succeeds without issue.

Is it possible I'm using the wrong endpoint for docker installation?

Steps to Reproduce

1. call /server with POST and required parameters to create a new server
2. receive UUID as a response from the above query
3. request server validation with /server/{uuid}/validate
4. receive "Validation Started." message via json

Example Repository URL

After attempting to reproduce validations not running on-request on a second coolify node (v4.0.0-beta.407), the validation endpoint succeeded without issue, so this might have been on my end. Would such a failure be logged anywhere?

API call doesn't work for me on beta.409 as well. Tried several times.
I create a new accessible server (fresh ubuntu 24.04), then do GET /validate, get "Validation Started." in response.

ValidateServer task in coolify container finishes very fast without installing anything. Property validation_logs in server response is null.

"Validate and Install" button in the GUI works fine with the same created server, able to install docker and run proxy container.
