Howdy,

Yesterday afternoon I upgraded my Jenkins CI server including installing the newest plugging versions. After upgrading to GitHub pull request builder plugin to version 1.11.2, the feature stopped working. With some investigating, I noticed all my configuration for the plugin had been reverted back to the default settings and there was no longer an access token. When attempting to generate a new access key, an error was thrown. Here is the error from the system log:

```

Any idea what is going on here? Didn't recall seeing any similar open issues. I will attempt to downgrade in the time being.
