Unable to add custom values to prefect.context

[sierrezinal]

with Flow("myflow", schedule=schedule) as flow:
    jobid = Parameter("jobid")
    prefect.context.update({'jobid': jobid})

Later on in my task, reading from the context returns None.

If you are using flow.run, the correct way to specify new context key / value pairs is via the context keyword argument:

flow.run(context={'jobid': jobid})

If you are using Prefect Cloud or Server, the API allows you to provide new key / value pairs for each ad-hoc run.

Also, it appears that you are using context incorrectly. You should never place tasks in context; if you are interested in passing data from one task to another, you should do so explicitly:

with Flow("myflow", schedule=schedule) as flow:
    jobid = Parameter("jobid")
    another_task(jobid=jobid) # will pass the jobid value to the task

flow.run(context={'jobid': jobid})

Aha. I need to RTFM more. Thanks.
