System information

Operating System: Windows
Architecture: x64 (64-bit)
Apple M1: no
Docker version: 20.10.6
Docker image used in act: catthehacker/ubuntu:act-latest
act version: 0.2.26-master ( e9c4609dca since 1891c72ab1 )

Expected behaviour

Print a proper errormessage and don't panic.

Actual behaviour

Panic after some failures without any cleanup.

Workflow and/or repository

workflow

on: push
name: no-panic-after-failure
jobs:
  nopanic:
    runs-on: ubuntu-latest
    steps:
    - uses: ./path/to/non-existent-action

Steps to reproduce

execute the provided workflow
act -W .\no-panic-after-failure\push.yml -v
older versions of act like v0.2.25 don't panic.

`act` output

EDIT 1
I'm mitigating missing cleanup due to this issue by github.com/ChristopherHX/act@425dc96daa

Act also panics if the docker daemon is unreachable.

Reason for this issue

The PR changed the meaning of the then executor to something like finally, therefore the pipeline executor won't stop on errors and continues with an invalid state. E.g. the action.yml file failed to load, then the next pipeline entry was expected to be skipped, but since it actually runs there is a null pointer access.

issue by https://github.com/ChristopherHX/act/commit/425dc96daa8884eb5cda4272acb71d55ff3e1489_ Act also panics if the docker daemon is unreachable. ## Reason for this issue The [PR](https://github.com/nektos/act/pull/840) changed the meaning of the then executor to something like finally, therefore the pipeline executor won't stop on errors and continues with an invalid state. E.g. the action.yml file failed to load, then the next pipeline entry was expected to be skipped, but since it actually runs there is a null pointer access.
