I’m currently receiving user input through

model = Parameter('model_name')

. I want to announce the user input in Slack via my state handler, but when I do it displays as

<Parameter: model_name>

rather than the actual user input. Does anyone have any suggestions on what I can do to display the user input?

Try

prefect.context.parameters["model_name"]

I got this error

AttributeError: 'Context' object has no attribute 'parameters'

🤔

That seems like it’s being evaluated immediately. How are you using the state handler?

Oo I see, I actually tried to print

prefect.context.parameters["model_name"]

directly in the flow, I’ll remove it and try again.

Ah the Flow block is not deferred

If I wanted to check if the user input was null, I can’t do that in the Flow right? It needs to be its own task?

Yes but we also have the

case

task to check the value of a task
