TaskRunner Docker with fileHandlingStrategy MOUNT error

[thomas-depierre]

Describe the issue

Using "fileHandlingStrategy: MOUNT" in "io.kestra.plugin.scripts.python.Script" with a dedicated docker task runner don't work.
("python: can't open file '/tmp/kestra-wd/tmp/43zhGVqpWVfcLvi6ZJRZiX/14502749081614047022.py': [Errno 2] No such file or directory").

- id: test
    type: io.kestra.plugin.scripts.python.Script
    taskRunner:
      type: io.kestra.plugin.scripts.runner.docker.Docker
      fileHandlingStrategy: MOUNT
    script: print("hello")

For scripts that process large files, the time spent mounting and unmounting volumes results in significant delays. We therefore tried using "MOUNT" to access the storage point directly, but without success. Even with the simplest of scripts, we still encountered errors.

Environment

• Kestra Version: 1.3.37
