+```
+from DIRAC.Core.Utilities.MySQL import MySQL
+File "/opt/conda/lib/python3.11/site-packages/DIRAC/Core/Utilities/MySQL.py", line 155, in <module>
+import MySQLdb
+ModuleNotFoundError: No module named 'MySQLdb'
+```
+This error occurred while importing `killPilotsInQueues` from DiracX via an import.
