+### Troubleshooting Cloud Pod Injection
+
+If you are on MacOS using the Docker Desktop App, and you want to inject the mysql pod, you might need to change some settings.
+
+The error message in LocalStack is visible when you enable debugging (`DEBUG=1`):
+
+```
+Different lower_case_table_names settings for server ('2') and data dictionary ('0').
+Data Dictionary initialization failed.
+```
+
+To fix this, go to the settings of the Docker Desktop App -> General, and then select `osxfs (Legacy)` for file sharing:
+
+![Change the Docker Desktop Setting](images/screenshot_docker_desktop_setting.png)
+
+Apply the changes, and restart LocalStack before attempting to inject the pod again.
