I'm getting the following error when trying to use an inline toml config for a gitlab runner:

ERROR: Failed to write / clone compose file

TRACE:
	1: failed to interpolate secrets into file contents
	2: did not find any value for variable runners

I'm wondering if this has something to do with komdo also trying to serialize/save the compose file as toml.

A workaround I used for now is instead of a UI defined compose I'm using the files on server option.

Here's my compose.yaml

services:
  dind:
    image: docker:20-dind
    restart: always
    privileged: true
    environment:
      DOCKER_TLS_CERTDIR: ""

I see. There is an option on Stack Config skip_secret_interp which enabling would fix this but I think you can only enable it using Resource TOML / Sync. I will review adding this to the UI.
