Error 1054036 Unable to build dimensions through rule file on MAXL on 21.1.0

This script had previously worked in the old 11.1.2 environment but I am unable to run it in the new environment in Linux.

The error message is vague, i can only see the following:

MAXL> import database APP.CUBE dimensions from local text data_file "FILE.txt" using server rules_file "RULEFILE" on error write to "ERROR.err";

 OK/INFO - 1053012 - Object [APP] is locked by user [ADMIN].

  ERROR - 1241101 - Unexpected Essbase error 1054036.

 OK/INFO - 1053013 - Object [APP] unlocked by user [ADMIN].

I have no issues manually loading through EAS lite or Essbase Web.

I read it might be an encoding issue but I made sure the file was UTF8, recreated the rule file but still not able to run via maxl.
