Note that if you hit this IllegalArgumentException, AFAIK, it meant you were passing an invalid value to a parameter which expected either an secret encrypted against a Jenkins key (format {…}) or Base64-encoded plaintext. The bug was that this mistake threw an unchecked exception which crashed startup. The fix is for it to behave as it did in earlier Jenkins versions: the invalid input is silently treated like an empty string. So I suspect that waiting for this plugin release was beside the point; you need to fix your JCasC YAML instead. From the stack trace, it seems that the input was neither encrypted, nor well-formed Base64; perhaps you were attempting to pass unencoded plaintext, which is not supported.

Should be fixed in https://github.com/jenkinsci/credentials-plugin/releases/tag/credentials-2.3.12

this fixed it
