I am just simply trying to bind this to a custom property. The URL endpoint in question is just a simple api that returns a json, no auth body, or headers are required from the endpoint. I get the following error which seems rather ambiguous.

Sounds too simple to be the answer, but the manual has the url enclosed with double quotes.

Yeah, the URL field is supposed to be an expression.

Thanks I just figured that out, which makes sense since at some point I will need the URLs to be dynamic, so string literals need quotes basically
