### What Operating System are you using (both controller, and any agents involved in the problem)?

Debian

### Reproduction steps

1. Create a Pipeline
2. Configure GitLab plugin
3. Create a GitLab project and set a webhook to the Pipeline
4. Test the webhook with issue event trigger (other triggers work fine)

### Expected Results

GitLab webhook trigger the Jenkins Pipeline

### Actual Results

Jenkins process the webhook. Prints this trace on the log:

may 17, 2024 9:40:01 A. M. INFORMACIÓN com.dabsquared.gitlabjenkins.webhook.GitLabWebHook getDynamic
WebHook called with url: /jenkins/project/-----

So the webhook is processed but the response is a 404.

### Anything else?

_No response_
