portainer: Unable to stop stack

Hi! First sorry for my english, i’ll try to do the best for explain my problem.

Bug description Unable to stop a stack created with portainer stack editor (docker compose)

When i try to stock the stack i have an error message: failed to remove a stack: Invalid template: "XXXX" (XXXX is the content of the first environnement variable)

Expected behavior Stop the stack to update it (add a volume for a container)

Portainer Logs There is nothing in portainer log (strange ?)

Steps to reproduce the issue:

1. Go to ‘Stack’
2. Select the stack
3. Click on ‘Stop this stack’
4. Confirm
5. See error
