 ## Troubleshooting

-### One of environement variable don't work as intended
+### One of the environment variables doesn't work as intended

-[**Note**][17]: GitHub reserves the `GITHUB_` environment variable prefix for internal use by GitHub. Setting an environment variable or secret with the `GITHUB_` prefix will result in an error.
+[**Note**][naming-conventions]: When you set a custom environment variable, you cannot use any of the default environment variable names. For a complete list of these, see [Default environment variables][default-environment-variables]. **If you attempt to override the value of one of these default environment variables, the assignment is ignored.**

-Currently, a GitHub workflow setting a `GITHUB_` variable don't ended up in error.
-And if a custom `GITHUB_` variable is in conflict with an official `GITHUB_` variable, the offical `GITHUB_` variable will override custom one.
+If a variable start to be used as default environment variable, the environment variable may have a different behavior than the expected one.

+On `pull_request*` workflows, the content will be `<PR-number>/merge` instead of the branch name.
+
+A possible workaround is to use `prefix` input available in `v4` version

 ```yaml
-name: Test
-on: push
-jobs:
-  build:
-    runs-on: ubuntu-latest
-    steps:
-      - run: echo ${GITHUB_REF}
-      # print "refs/heads/v3.x"
-      - run: echo "GITHUB_REF=one_value" >> "$GITHUB_ENV"
-      - run: echo ${GITHUB_REF}
-      # print "refs/heads/v3.x"
-      - run: echo "GITHUB_REF_SLUG=another_value" >> "$GITHUB_ENV"
-      - run: echo ${GITHUB_REF_SLUG}
-      # print "another_value"
+- name: Inject slug/short variables
+  uses: rlespinasse/github-slug-action@v4
+  with:
+    prefix: CI_
 ```

-  </p>
-</details>
+Then `${{ env.CI_GITHUB_REF_NAME }}`, and `$CI_GITHUB_REF_NAME` will serve the behavior of this action.
+And `$GITHUB_REF_NAME` will serve the behavior of GitHub Action.
