invoke JenkinsServer#createJob Error

I use jenkins 2.164.2，and i can invoke jenkinsServer#getJobXml to get jobXml，but when i invoke jenkinsServer#createJob("my-test-job", jobXml, true) occurs the following error message:

org.apache.http.client.HttpResponseException: Internal Server Error
at com.offbytwo.jenkins.client.validator.HttpResponseValidator.validateResponse(HttpResponseValidator.java:11)
at com.offbytwo.jenkins.client.JenkinsHttpClient.post_xml(JenkinsHttpClient.java:375)
at com.offbytwo.jenkins.JenkinsServer.createJob(JenkinsServer.java:389)
at com.offbytwo.jenkins.JenkinsServer.createJob(JenkinsServer.java:359)

as anyone can help me?

Start by tracing JenkinsServer#createJob through JenkinsHttpClient.post_xml and HttpResponseValidator.validateResponse, the locations named in the stack trace. Reproduce the call with Jenkins 2.164.2 and the reported job XML; done means identifying the cause of the HTTP 500 or documenting the additional information needed to diagnose it.
