[PepijnB]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

in line 159 of entrypoint.sh gh is used to set the authentication. If gh is not installed this will fail with exit code 127 (not so descriptive).

There is a check however in sync_template.sh, however this is exectued later.
Please consider moving the check to the entrypoint.sh

Expected Behavior

Get a proper error message. Something like: github-cli gh is not installed. 'https://github.com/cli/cli'

Current Behavior

Process completed with exit code 127.

Steps To Reproduce

No response

Possible Solution

Additional Information/Context

No response

Template sync version Version

v2.4.1
