Managed to make core-14 failed silently

[jd-imi]

In core-14, I forgot to update the port from core-13, so, 8013 was left instead of 8014.
check.sh didn't gave a "Failed" message but the check in dockerlings didn't work (it was because check.sh returned with a non-null value)

The two last lines of the log I had:

--> Accessing web app to increment counter to 1...
--> Shutting down Docker Compose project...

There was no "Failed" message because the curl command returned with a non-null value (7 in this case), so the script exits immediately.

I get a "Failed" with this (and the return code is still non-zero):
