Title: Craft CMS hangs when deleting a field then throws 504
ThreadText: # Craft CMS hangs when deleting a field then throws 504
  
  (Asked by: username_0 on 2020-07-30)
  
  We have an instance of Craft CMS running that has a lot of content entries and a lot of fields, using Neo and SuperTable. At some point, something changed and now when we try to delete one of the fields the CMS will just hang until it eventually throws a 504 error and sometimes seeing an error like `sql timeout exceeded error`. Any idea how to track this down?
  
  Some additional info, I keep seeing this error in the logs `yii\web\NotFoundHttpException: axios.min.map does not exist.`
  
  Also getting a failed POST request for /index.php?p=admin/actions/fields/delete-field
