Is windows OS supported by this action or not? Thank in advance

I got the same error on a linux runner when my private key was not correct (unintentional linebreak). Generating a new one in the app settings (just to be sure) and using that fixed my problem.

@RobinMaas95 thank you for your feedback! The thing is the same key works fine on Linux machine. I have to run some jobs on Linux, some on windows due to some dependencies. And the key doesn't work properly on windows. I had to create a python script to generate it instead, and it works. So, pretty sure, something might be wrong with this action

Check your line endings. My --- BEGIN RSA PRIVATE KEY --- had the /n stripped somehow.

@sijjay could you confirm if the above comments helped resolve your issue?
