We developed a plugin using the confluence sdk, and have implemented our own custom scheduled task, and occaisonally we run into an error where the scheduled task returns the following error:
Error: `No content to map due to end-of-input

if we manually trigger the custom scheduled job from the Configuration >> Scheduled Jobs screen and click the “run” button our custom plugin works and executes fine without that error, it only returns that error when the scheduler is trying to execute it.
we are running confluence 7.19.1, and we have an experiment with a datacenter instance running the same version and we see the same result between server and datacenter.
Our Job Runner code is as follows:

else

}
}
I was curious if anyone else has run into this issue before when developing a custom plugin using the job runner pieces. We have tried to add additional logging, but since it happens when its scheduled vs manually triggering the task, its hard to locate and find those log messages in all of the logs.
