I'm running a Scheduled flow that calls another flow using the

startFlowRun

method. Initially when I was calling the first flow without using the

wait

parameter, the flows worked fine, but after I added the parameter, the parent flow failed with

TypeError: Object of type SUCCESS is not JSON serializable

. I was wondering if this is a known issue. Prefect version is 1.4.0

Hey @Arun Giridharan do you have a simple example of the code you're running?

@Mason Menges I'm running into essentially this error: https://github.com/PrefectHQ/prefect/issues/4975, I tried wrapping the wait_for_flow_run in a wrapper but that didn't work
