Hi, trying to run large number of stacks via cloudposse/github-action-matrix-extended action. It seems that input for the inner action that's called by it, i.e. cloudposse/github-action-jq is too long. I'm getting:

An error occurred trying to start process '/home/runner/actions-runner/cached/2.336.0/externals/node24/bin/node' with working directory '/home/runner/work/infra-github/infra-github'. Argument list too long

It's 136,054 bytes long. Is this anything you've faced before?
