Solved -execution of command did not complete successfully with exit code [255] - Informatica

A command task invokes a batch script which could be doing anything and has ECHO or REM statements. The workflow fails with the following error in workflow log:

LM_36623 : Command task instance [cmd_SFTP_command]: execution of command [Command1] did not complete successfully with exit code [99840]

Or

LM_36623 : Command task instance [cmd_SFTP_command]: execution of command [Command1] did not complete successfully with exit code [255]

Cause

This occurs when the batch script containing the SFTP connection contains REM and ECHO statements which causes the command task to fail. This is a known issue and CR 203903 exists.

Solution

To run the task remove the REM and ECHO statements from the batch script and start the batch script from the command task.
