Just checking, in your API call is your True lower case?
...
"hasUniqueValue": true,
...
Did that make a difference?

Thank you Mike for your reply, The SS you are seeing above is taken from postman, I don't think lower case will work there.In documentation, i found we can't set other property unique because email is already unique field present there.if this is not the case, i have not found solution yet
