I do see similar issue on Windows. Any workarounds?

👋
Any possibility to re-open this issue?
I see the same problem and it seems that this possibly is patched in the runner.

I can confirm the fromJson is not working in version 0.2.18. My example is similar to https://github.com/nektos/act/issues/330#issue-672533677

This was not fixed by #352. Is there something tricky about this?

I have similar issue using https://github.com/dflook/terraform-plan in my CI

Looks like

runs:

  entrypoint: /entrypoints/plan.sh

First slash in entrypoint is causing an issue.
