CriticalXStreamException in authorizationStrategy

any solution for this error

Hi, when requesting help from others, it helps IF YOU:

  • Provide a relevant title,
  • Provide the error message as text, not an image of text. It’s harder to read and not indexable.
  • Version of Jenkins, installation information, maybe relevant plugins and versions
  • Provide some context as to what was happening/what you were when the error was triggered. Was this a configuration change, a job, an upgrade, etc.
  • Only provide images if they convey additional value

So, at this time, no. I don’t even look at images of stack dumps.
