[BUG] Missing validation for watch causes watch to break #11507
Description
Description
Empty action in the watch definition can break watch, especially with path present.
This should at least fail on invalid definition.
Steps To Reproduce
I have this watch definition present:
develop:
watch:
- action: sync
path: ./src/
target: /app
ignore:
- _build
- path: ./src/
When running docker compose watch, the output for the configuration is:
Watch configuration for service "backend":
- Action sync for path /home/...
- Action for path /home/...
When a file is changed, the end result is this, watch is completely broken:
Syncing "backend" after changes were detected:
- /home/.../index.html
- /home/.../index.html
,tar: Substituting `.' for empty member name
Ytar: .: Cannot open: File exists
tar: Exiting with failure status due to previous errors
WARN[0046] Error handling changed files for service backend: 1 error occurred:
