Why facing error as 'An error occurred when attempting to delete the snippet...' when trying to delete kickstart snippet on Red Hat Satellite?

Issue

• When trying to Kickstart Snippets by clicking on "Delete Snippet" from Red Hat Satellite webui, it shows the following error:

  An error occurred when attempting to delete the snippet <strong>test_snippet</strong>. 
  

  Within the Custom Snippets Overview the snippet which wanted to delete shows: $SNIPPET('spacewalk/1/test_snippet ') As you can Can see that there is blank space before the '. But the "delete snippet" from webui don't have any blank space.
