 ## Troubleshooting
 
-### Errors when importing a repository on dbt Cloud project set up
-If you do not see your repository listed, double-check that:
-- Your repository is in a Gitlab group you have access to. dbt Cloud will not read repos associated with a user.
-
-If you do see your repository listed, but are unable to import the repository successfully, double-check that:
-- You are a maintainer of that repository. Only users with maintainer permissions can set up repository connections.
-
-If you imported a repository using the dbt Cloud native integration with GitLab, you should be able to see the clone strategy is using a `deploy_token`. If it's relying on an SSH key, this means the repository was not set up using the native GitLab integration, but rather using the generic git clone option. The repository must be reconnected in order to get the benefits described above.

 If you receive a schema-related error message referencing a <i>previous</i> PR, this is usually an indicator that you are not using a production job for your deferral and are instead using <i>self</i>.  If the prior PR has already been merged, the prior PR's schema may have been dropped by the time the CI job for the current PR is kicked off.

+id: gitlab-webhook
+---
+
+When you connect dbt Cloud to a GitLab repository, GitLab automatically registers a webhook in the background, viewable under the repository settings. This webhook is also used to trigger [CI jobs](/docs/deploy/ci-jobs) when you push to the repository.
+
+If you're unable to trigger a CI job, this usually indicates that the webhook registration is missing or incorrect.
+
+To resolve this issue, navigate to the repository settings in GitLab and view the webhook registrations by navigating to GitLab --> **Settings** --> **Webhooks**.
+
+Some things to check:
+
+- The webhook registration is enabled in GitLab. 
+- The webhook registration is configured with the correct URL and secret.
