I have a parameter in a deployment I want to run with an array of integers. But when I try to input anything in the Orion UI shown below, I get an error…

prefect.exceptions.ParameterTypeError: Flow run received invalid parameters:
 - capsule_ids: value is not a valid integer
 - capsule_ids: value is not a valid list

I have tried

[1,2,3]
1,2,3
1\n2\n3

And they all fail. It seems like prefect is treating my input as a string because when I inspect the parameters, they look like

capsule_ids:"[1,2,3]"
capsule_ids:"1,2,3"
capsule_ids:"1\n2\n3"

So my question is, how do you enter a list into orion UI?
