I am running the Ignition gateway through a container (WSL2-based) on a Windows system. I am running Ignition Designer on Windows

Steps to Reproduce

  1. Open designer to a project
  2. Create a new report
  3. Under schedule, go to actions
  4. Enter a valid Linux path. Examples below.

Expected Behavior

Designer should accept the valid path.

Actual behavior

Ignition throws an error:

Attempted Action could not complete.  WARN: Error in running distribution Save File for report ReportName-- Unable to write PDF to file '/usr/local/bin/ignition/my-example-path/file.pdf

Additional examples

For simplicity, anytime the %% appears below, it is the /usr/local/bin/ignition/ directory on the container system. In addition, I will try having the filename as outputs/today/file.txt.

Folder Path Result
~/folder Fail, and %%/~/folder is created (yes, ~ is the name of the folder)
folder Fail, but %%/folder/outputs is created
C:/folder Success, output to %%/F:/folder/outputs/file.txt, there F: is the name of the folder.
/home/ignition Success, output to /home/ignition/folder/outputs/file.txt, as expected.

As shown, the behavior is wildly inconsistent. It can write to it's %% folder, but ONLY if it is using a "Windows path". Additionally, even on failures to save the file, the folder paths are still created, even if they use reserved characters.
