I've noticed a strange behaviour. My form with Qrules and a secondary data connection (GetProfileByUsername) errors on opening.
The following query failed: GetUserProfileByName (User: , Form Name: tf1, IP: , Connection Target: , Request: , Form ID: urn:schemas-microsoft-com:office:infopath:tf1:-myXSD-2016-05-26T11-51-03 Type: DataAdapterException, Exception Message: The remote server returned an error: (500) Internal Server Error.
A user with the account name could not be found. --->
However the same form without Qrules works with no issue.
