Cannot run devenv up anymore

[TimisRobert]

Describe the bug
When running devenv up, the following error is given:

error: unexpected argument '--task-file' found

  tip: to pass '--task-file' as a value, use '-- --task-file'

Usage: devenv-tasks run [OPTIONS] [ROOTS]...

For more information, try '--help'.

To reproduce
devenv init, enable postgres service for example, then devenv up

Version
devenv 1.9.0 (x86_64-linux) non-flake
nix (Nix) 2.28.5
nixos 25.11.20250921.554be64 (Xantusia)

PS: this happens only when using process-compose, it works using any other process manager

Thanks!

This is affecting me.

In my devenv.nix I have:

process.manager.implementation = "honcho";

Is there anything else needed to switch from process-compose?

My error is:
