I'm working on some JavaScript on my form and so I have been watching the console messages to make sure all is well. 

I noticed that when I have a date field set as required and then change it's value it throws an error.

I am not using trim anywhere in my code and if I make the field so it is no longer required the error does not happen. 

It does not matter if I set required in the "rules" or by checking the "required" checkbox. 

It does not seem to be causing issues in running my code, I just thought I should report it just in case it could be causing others issues. 

EDIT: A snip of my code:

async function updateAuditDate()
{
  let currSigTxt = LFForm.getFieldValues({fieldId: currentUserSigTxtFieldID});
  
  await LFForm.setFieldValues({fieldId: theAPCompleteTxtID}, currSigTxt);
  LFForm.changeFieldSettings( {fieldId: theAPDateID}, {subtext: currSigTxt} );
  
};

LFForm.onFieldChange(function(){ 
  console.log("Audit Date Changed");
  updateAuditDate();

}, {fieldId: theAPDateID});
