Loop block doesn't work with Twilio API

Hi, I'm trying to use a loop block with the Twilio API. But neither the value.XXX nor the index.XXX variables work. They don't validate - I can only get valueOf (which doesn't help). See attached image for details.

Any idea why?

Hi @mercu,

We identified a bug where variables in scope are not detected correctly in form fields for some resources (including Twilio). A fix for this will be deployed tomorrow. In the meanwhile, you can still use value in that block although the validation is incorrect. This is only a visual bug and won't affect execution.
