When we try to access the current pipeline status by executing the following request:
<pipline job name>/lastBuild/wfapi/

We sometimes get the following exception when the pipeline is running:

Note that it works most of the time. But at some point, during the pipeline build, we get always the error above. After some time everything is ok and we get valid json again.

Seems to happen only when showing a pipeline where a parallel step is currently running. I hope this help investigating this.

mschwartau Do you have a snippet of pipeline code that will reproduce the issue? It should only occur when a you have parallels in progress (which is why it disappears), so you should be able to reproduce it more consistently by adding sleep steps in place of some longer-running operations.

This seems to break 100% of the time. It only breaks if the second task ends before the first

stage 'test' , {
parallel([
unit: {
node('unit') {
dir('some_folder')

{ sh "sleep 5" sh "sleep 10" sh "sleep 15" sh "sleep 20" sh "echo 'hello'" }

}
},
otherunit: {
node('unit')

{ sh "sleep 10" sh "echo 'goodbye'" }

}
])
}

Sorry for the bad formatting, it seems I cannot wrap this in preformatted text.
