Fail to open stream require(contrib/yarn.php)

[Edvinaz]

Hello, stuck with the problem... I used deployer to deploy to production from command line, but decided to implement github actions to automatically deploy, but i getting error that fails to open stream:
PHP Warning: require(contrib/npm.php): Failed to open stream: No such file or directory in /home/runner/work

used official Github Actions example from Deployer documentation

Try to run dep locally. Follow install instructions

locally it works fine, but github action fails, is there some instructions to follow what could be wrong?

found out that i needed to use composer install before deploying
