You're using Signature Slayer and notice the error 'Missing delete permission for SObject Document' come up.


 

This error is most likely to show up when using the undo feature after slaying a file or image.

​​​​​​​Users of Signature Slayer need to have delete permission on the standard Document object in Salesforce.

Unfortunately, packaged permission sets cannot provide this sort of access to standard objects, so it needs to be manually added by an administrator in the Org.
