We use the parameterized-remote-trigger-plugin via groovy scripting.

ServerA is running Jenkins 2.204.1

ServerB is running CloudBees Jenkins Enterprise 2.263.2.3

I am able to workaround the issue by placing the call to triggerRemoteJob with a catchError block, forcing the build and stage status to 'SUCCESS'.

groovy scripts running on ServerA have no problems triggering jobs on ServerB

groovy scripts on ServerB are throwing errors triggering jobs on ServerA

• the job on ServerA starts
• the job on ServerB reports an error

Groovy script does:

def remoteTestJob = triggerRemoteJob remoteJenkinsName: "remote-server",
    job: "remote-job",
    token: remote-job-token,
    parameters: "UPSTREAMBUILDNAME=mybld",
    maxConn: 5,
    shouldNotFailBuild: true,
    blockBuildUntilComplete: false

ServerB Jenkins Console output:
