Error on logging into powerapp

Posted on by samiHaque

I have created a PowerApp, whereby users can log into it using their office 365 credentials. The app works greats however, the end users are always getting the following error when they log in for the first time. When they exist the app and log back in again they don't get the error. Can someone help with what I might be doing wrong.

Office365Users.UserProfile failed: The function 'UserProfile' has an invalid value for parameter 'userId' - a blank value was passed to it where it was not expected. Please make sure that a valid argument is passed to the function.

Appreciate any help.

@samiHaque I faced the same error yesterday. The issue seems to be that the value for Office365Users.UserProfile loads a little later than the app. So the formula you are using that function in to fetch the User information see a blank value initially which then results in an error.
I resolved that error by handling it using IfError(). Depending on your use case you can use other error handling methods described here.
