Permission denied while executing node binary on Ephemeral runners

[apoorva-marisomaradhya]

Hello!

We have self hosted runners which are ephemeral in state, and we have started seeing the below Permission denied errors
Error: An error occurred trying to start process '/opt/actions-runner/externals/node20/bin/node' with working directory in the workflow
'/opt/actions-runner/_work/gandalf/gandalf'. Permission denied
FWIW the error goes away if we re-run the workflow..

Any help to resolve this issue will be highly appreciated.
Let me know if more information is needed to debug, will be happy to share the same.

Thank you,
Apoorva

This sounds like a upstream issue? are you trying to write to a non existing directory that is yet to be created?

Agree this is most likely a problem related how you setup the runner. By re-running you creat a new runner (ephemeral) and all persisted data is gone. A permission error could be related to permissions used by the agent and your job. For example running as non root and using docker in several steps can cause permissions clashes on the file system.
