Oasis Montaj gxpy edb.lock() issue

TimNixon1

Hi All. I am trying to write a custom coordinate conversion as n extension in Python. I am coming across an error where I get the current edb and lock it to create a db handle to read and write data in to the database. My code looks like this (for testing this error only).

def rungx():
gxpy.utility.check_version("9.2")

def rungx():

  gxpy.utility.check_version("9.2")
  with gxpy.gx.gx():


      edb = gxapi.GXEDB.current()  # current edited database


      try:

          gdb = edb.lock()          # lockedb, get GXDB handle 


          if gdb is None or gdb.is_null():  

              gxpy.utility.display_message(

                  "Lock_EDB returned an invalid database handle."

              )

              return

Any clues as to why I can not lock the edb to get a db ahndle would be appreciated.
