Privacy rules on the User data type.
Also, your Employer ID should probably an Employer (data type) rather than an ID (text).
Thank you George. I appreciate your quick response.
Question: Would privacy rules affect the second search but not the first one?
I will test on the data types.
Yes, because you’re searching for a User that isn’t the Current User.
Thank you George. It was a privacy rules issue. I was able to fix it with your advice.
