Hi guys
Over the past couple of weeks, we've had some rare instances where the User() function is not serving up the App user's details.
We have a patch to a SharePoint list at some point, and for the part where we're writing to a person field and state the 'Claims', we use a variable (defined in the OnStart of the App) which concatenates i:0#.f|membership| with User().Email.
Some users have seen the error message: The requested operation is invalid. Server Response: [our SP List] failed: The specified user i@0#.f|membership| could not be found - which suggests to me that the User().Email part is blank and it's trying to just pass the variable with only the i:0#.f|membership| string within it.
It's a highly used App that has been in place for almost a year, with hundreds of uses a day - but there's only been 3 or 4 instances across the past fortnight, so I'm not too concerned about it - in every instance reported to us, we've asked them to refresh and it's not reoccurred.
It's just odd that it's started happening all of a sudden (nothing else has been added to the OnStart during this period) and I'm wondering if anyone else has run into the same issue?
