I did suspect that line 133 could only contain certain values, it looks like your trying to have organisation name added.
your jumping from the ost_ticket table (user id) to a lookup in the user table (org_id) to the organisational table (name)
the naming seems to be 'user' to reference the table name
a double underscore __ to skip over
org for the organisation table
__ to skip over
and finally 'name' the field you need
so try this 'userorgname' it seems to work for me
