And you get the error when you try to run it I presume The name=main block isn t executed so you can get the `name input` argument into your flow several ways Under `parameters` in your deployment YAML manifest you can add a `name input marvin`

Jeff Hale · Answer

Or you can add the parameter from the GUI

Wei Mei · Answer

aha added in via the gui and it worked

Jeff Hale · Answer

Or you could make a default argument in this line `def hello flow name input `

Thanks Jeff I am in the process of playing with 2 0 as all my flows are 1 0

Wei Mei · Answer

I use Parameters extensively in 1 0 and am a bit confused as to how this changes in 2 0

Cool As you can see there are a number of ways to set params in Prefect 2 so let us know if there is a feature missing Have fun exploring
