[ISS Support Case] J5 PI AF Error
Last updated: October 17th, 2025Description
Within industraform where we utilize a PI AF datasource connection, our attributes are not populating with their test data when we simulate a test form. We are seeing the below error when we run the test: "Error retrieving external data: Invalid" Looking at the J5 PI AF logs on the app server, we can see the below error repeating for all the attributes which have been setup: 05/01/2025 14:02:45 Type : System.Collections.Generic.KeyNotFoundException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 Message : The given key was not present in the dictionary.

We recently migrated our stage DB from version 2012 to 2019. We had some driver mismatch issues but were able to fix that particular issue. Now we have noticed that we have duplicate profiles and disable accounts within our stage app. Around 1/3 of the users are showing as disabled. LDAP sync is disabled from the J5 system management console so we are not sure what could have caused this, but looking at the way the profiles are setup, it definitely looks like it synced with LDAP somehow.
