I’m having an FME workspace that has a custom transformer that is set to parallel running.

when running the workspace from FME form there is no issue, everything runs smoothly.

If I want to schedule this workspace (due to lack of FME flow) using Windows task scheduler the workspace terminates because none of the cild processes run succesfully.

They all crash with the message ‘Access is denied’. This is the commandline for a child process:

When not running in parallel, there is no issue.

anyone an idea what can cause this issue? it’s really fustrating on how to solve this?

      What Windows account have you set the scheduled task to use?

      Same account as when I develop the workspace.

      It does run fine with the schedule as long as there is no parallelization.

      Hmmm, thats really bizarre. Might be worth opening a support ticket with Safe directly as it could be an underlying issue/bug - https://support.safe.com/hc/en-us/p/support

      ​@tva - did you ever solve the issue? I’m seeing effectively the same thing.

      Hi ​@tva! I totally agree with ​@hkingsbury. It’s definitely worth us at Safe to dig into the “Access denied” issue. Would you kindly submit a ticket so that our team can look into this further (if you haven’t already)!

      When submitting your ticket, please provide the following (if available):
      - Details about the environment used (e.g. platform and OS version, FME Flow deployment, any other dependencies, etc.)
      - Any relevant log files (e.g. translation logs, job logs, fmeserver.log, etc.)
      - Any relevant screenshots (e.g. errors, configurations, etc.)
      - The workspace (or sample workspace) that you are encountering issues with. Please be sure to include any required data or custom transformers needed. If, possible please send this as a template (.fmwt).

      And generally any other information you think would be helpful to reproduce and diagnose this issue 🙂



       

      Happy FME-ing!
