 You now have a running Airflow server that can communicate with Sonador.
 
 
+### Troubleshooting
+
+**Relation session does not exist**
+
+If you encounter the following error:
+
+```bash
+  File "/home/airflow/.local/lib/python3.8/site-packages/sqlalchemy/engine/default.py", line 608, in do_execute
+cursor.execute(statement, parameters)
+sqlalchemy.exc.ProgrammingError: (psycopg2.errors.UndefinedTable) relation "session" does not exist
+LINE 2: FROM session 
+```
+
+You must exec into the `airflow-webserver` container and run the following command:
+
+```bash
+airflow db upgrade 
+```
+
+**No user found / issues logging in**
+
+If you cannot login, manually create the Airflow admin account in the `airflow-webserver` container by using the following command:
+
+```bash
+airflow users create [-h] -e EMAIL -f FIRSTNAME -l LASTNAME [-p PASSWORD] -r ROLE [--use-random-password] -u USERNAME
+```
