"Private keys with passphrases are not supported." for keys with no passphrase

[navicore]

I have a private github repo and am setting private_key with a passphrase-less key but am getting error:

resource script '/opt/resource/check []' failed: exit status 1

stderr:
Private keys with passphrases are not supported.

I'm guessing I'm not setting the private key properly. Any hints or places to look for errors appreciated.

Check the formatting of your private key? Maybe it was botched when added to the YAML.

sry, got it working with parameters and the cli --var so I'm unblocked. must have something messed up in my secrets file.

I had this problem when I changed my vars file from yaml to JSON. What mattered to me was this:
The start of the private key begins with a | character. Make sure your pipeline preview looks like this:

  name: source
  source:
    branch: master
    private_key: |
      -----BEGIN OPENSSH PRIVATE KEY-----
...

And the end of the private key has a newline.

When I had both of those (I was missing the final newline), it worked again.
