Unexpected Error Please contact your system admin

Hey all,

Fairly new to this platform but i’ve come across a critical error (i suspect on my behalf), i was exploring the user sessions and shut all down but mine…i’m now receiving this error:

Hi James,

Please attach app.log - it should contain a meaningful info about the error.

Attached :slight_smile:

app.log (201.1K)

Look at the last exception in this file (which probably aborted the server start):

Caused by: java.lang.IllegalArgumentException: Property 'anEmployee' not found in payroll2$TimeEntry

Something is wrong with this attribute. What type is it? Could you provide the source code of the entity?
