-### A deployment job failed with "This job could not be executed because it would create an environment with an invalid parameter" error
-
-> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/21182) in GitLab 14.3.
-
-FLAG:
-On self-managed GitLab, by default this bug fix is not available. To make it available per project or for your entire instance, ask an administrator to [enable the `surface_environment_creation_failure` flag](../../administration/feature_flags.md). On GitLab.com, this bug fix is not available, but will be rolled out shortly.
-
-If your project is configured to [create a dynamic environment](#create-a-dynamic-environment),
-such as a [Review App](../review_apps/index.md), you might encounter this error
-because the dynamically generated parameter is invalid for the system.
-
-For example, if you have the following in your `.gitlab-ci.yml`:
-
-```yaml
-review:
-  script: deploy review app
-  environment: review/$CI_COMMIT_REF_NAME
-```
-
-When you create a new merge request with a branch name `bug-fix!`,
-the `review` job tries to create an environment with `review/bug-fix!`.
-However, the `!` is an invalid character for environments, so the
-deployment job fails since it was about to run without an environment.
-
-To fix this, you can:
-
-- Re-create your feature branch without the invalid characters,
-  such as `bug-fix`.
-- Replace the `CI_COMMIT_REF_NAME`
-  [predefined variable](../variables/predefined_variables.md) with
-  `CI_COMMIT_REF_SLUG` which strips any invalid characters:
-
-  ```yaml
-  review:
-    script: deploy review app
-    environment: review/$CI_COMMIT_REF_SLUG
-  ```
