Issue Description

in powershell workflow, a string default parameter is showing an error saying it needs to be a "simple value" like an int or a string. and it is a string.

Do you get the same marker in the ISE? I think that would be coming from PowerShell.

[dotps1]

I do get the same thing in the ISE, but based on the error I just don't understand, it says must be simple values, int or string. that is a string.

I am having trouble reproducing this, @dotps1 are you still running into this issue?

[dotps1]

its been like a year ¯_(ツ)_/¯

[dotps1]

but yes it is still happening:

[SeeminglyScience]

@dotps1 I know you're probably not looking for an answer anymore, but it's because the parameter is typed as a string array. Even though the default value specified in the script is a string, it would need to first be converted to an array for the typing to match. Workflows are compiled, so they tend to be a good deal more strict than normal PowerShell.

[dotps1]

good enough for me.

@dotps1 Hi Thomas, do you debug Workflows in VS Code? Can you point me at any resources that can instruct me how to do it?
Thank you
