Fail and error message when using "Markdown to Notes"

I receive the following error when using the action “Markdown to Notes”:

Could anyone share advice on the steps I would need to take to fix this? Thanks.

Do you have a folder in Notes called Testing?

If not change line 6 in the action’s script step to your actual folder name.

Thank you @sylumer, that solved it.

How do you find the name of the folder?
