Current Limitation

Currently, when there's a newly added field to an object, we validate for permission if it can be added

if (newKeys.length > 0) {
      // adds a marker that new field is being adding during update
      runOptions.addsField = true;
      const action = runOptions.action;
      return schema.validatePermission(className, aclGroup, 'addField', action);
 }

validatePermission can throw an error depending on whether the field can be added or not.
Actual Error :- ParseError: Permission denied for action addField on class _User.
I think would be better to log the newly added field if in case validatePermission throws error

Feature / Enhancement Description

Log the newly added field if the validation fields, as it provides better information on what went wrong.
Expected Error :- ParseError: Permission denied for action addField on class -User.

Start with the shown update path where newKeys are detected and validatePermission is called for the addField action; trace how the newly added field and permission error are represented. Done means a denied addField validation reports the relevant field in the error, with behavior confirmed by the existing permission-validation tests.
