It it possible to write down your job hierarchy ?
The deletion of jobs is not an easy task. Currently it relies on the build history, if it is incomplete or wiped I think it can produce NPEs, I'll check into this.
Thank you for the report.

The structure is:

SND-Deploy-AA_Generate -> (template) SND-Deploy-AA_Template = SND-Deploy-AA_Stream_DO_NOT_RUN and SND-Deploy-[JOBS A, B, C... x 100]

Only one the concrete jobs had a job history. The others had never been run.

You generate 100 jobs so maybe the build history for the parent job generator is not complete.

I guess I must find a way to keep track of the generated jobs outside of build history or find a clever way to find which jobs are to be deleted.

I see what you mean. At one point or another I needed to cancel the generation because of errors. Also, I only kept the last 10 runs of the generation to the logs definitely rolled off.
