updateUserFields stopped working

This function worked fine for me couple of weeks ago, now I can’t get it to work to update my custom fields.
Backend:

export async function updateUserFields(userId, firstName, lastName, unitNo, floor, ownerName, agreedDate, agree) {
  let userResponse  = await wixUsersBackend.updateUserFields(userId, {
    "firstName": firstName,
    "lastName": lastName,
    "unitno": unitNo,
    "floor": floor,
    "unitowner": ownerName,
    "agreeddate": agreedDate,
    "agreedtoterms": agree
   
  } )
    .then( () => {
      console.log("UPDATED");
	  
    } )
    .catch( (err) => {
      console.log("NOT UPDATED");
	  console.log(err);
	  
    } );
}

I have also tried with UpdateMember and updateContact function, but no luck.
Seems to me that they changed something but it does not seem to be documented?

I am having the exact same issue with the updateMember function. Although I do see that the wixUsersBackend . updateUserFields is a depricated function.

I get the following error when trying to run the updateMember function.

{
    "message": "Error: Unable to handle the request. Contact the site administrator or view site monitoring logs for more information.",
    "name": "Error",
    "stack": "Error: Unable to handle the request. Contact the site administrator or view site monitoring logs for more information.",
    "_elementoryError": true
}

Not sure if you are seeing the same thing or not.

I do not get any errors in the Log… But it is not changing anything except “default” fields… Let me know if you find a solution on this.

Thanks for your inputs!
