Can't find 'action.yml', 'action.yaml' or 'Dockerfile'

[imgalli]

Describe the bug

We're using your semantic release action (thanks!) in a release workflow which has been working fine though we've had a blip where the following error was thrown. One thing to note is that we're using custom runners rather than the standard GH action runners.

2021-03-10T11:26:09.3830758Z ##[error]Can't find 'action.yml', 'action.yaml' or 'Dockerfile' under '/tmp/github/_actions/cycjimmy/semantic-release-action/v2'. Did you forget to run actions/checkout before running your local action?

Workflow

Release, there is a checkout step many steps ahead of the semantic release one.

Additional context

As said, we're using a custom runner which could be one key difference. That said the error is quite straightforward sounding yet odd.

Here's an excerpt from our workflow file
