Hi all, Is there a way to pass-on current context to next flow run triggered using

FlowRunTask

task? Basically, I am sending some context parameter while creating a flow run using python client's

create_flow_run

method. The flow upon completion triggers other downstream flows. Now, I want the context that I originally sent, available to downstream flows but I haven't had any success so far.

Hi @Sandeep Aggarwal, looks like no since

FlowRunTask

doesn’t accept

context

right now (would eventually expect it to get passed along here https://github.com/PrefectHQ/prefect/blob/master/src/prefect/tasks/prefect/flow_run.py#L109), but I think that is a feature we can add pretty quick! I can make an issue from this ticket but first let me check if that fixes your issue. I think in that situation then your Flow A (kicked off with the python client) would have in it a node of

FlowRunTask

to kick off Flow B. You want to send context from Flow A (lets say

prefect.context.foo=bar

) to that Flow B. I just want to clarify that in practice, Flow A would need to have, or be able to re-derive just the added context (just

foo=bar

) since we probably don’t want to send the entire context object from Flow A straight into the

FlowRunTask

to ship to Flow B (as it has a bunch of other prefect sutff in it too). Would that achieve your use case?

Thanks @Laura Lorenz (she/her) for your reply. Yes exactly this is what my use case is and selectively passing the required context to Flow B will work.

@Marvin open “Expose context arg in FlowTaskRun task”

@Laura Lorenz (she/her) I have a very similar use-case. I am trying to implement backfill functionality on a flow that uses result caching using templated targets. Passing the context to that flow from

FlowRunTask

would be quite a useful feature.
