Hi everyone, I stumbled upon an error as the prefect engine serializer tried to pickle a task result:

TypeError: cannot pickle 'lxml.etree.XMLSchema' object

Of course the result of one of my task is of this type and I would prefer not to change it. I tried to launch that process again with

config.flows.checkpointing = "false"

in the

~/.prefect/config.toml

file but I got the same error... This is an error that I cannot reproduce locally with

prefect run <flow>

. Do you guys have any leads on how I can solve this issue or at least reproduce the error locally?

config.flows.checkpointing = "false"

gets overridden in Cloud backed runs. You need to turn it off in the task level

@task(checkpoint=False)

.

oh. But I am hosting the prefect server, would that change anything ? I'll try to put this option in the decorator nonetheless

it works the same way for Cloud and Server

yay it worked \o/
