I can print the userRecord.uid as an admin just fine. However when I return this variable as follows:

return userRecord.uid

On the client side I have

var response = FirebaseFunctions.instance.httpsCallable('watergreen');

when I print this response variable I get

Instance of 'HttpsCallableResult<dynamic>'

I've also tried to change var response into:

HttpsCallableResult<dynamic> resp

and

Map<String, dynamic>

but I can't print the uid on the client.

What am I doing wrong here?
