Error 400 in HTTP Module

I’ve been trying to fix this for a week, for some reason I can’t get it to connect properly without putting an error module in. Also it’s not making any calls. I have my Twilio linked, ive made my trigger so it’s only meant to call one number from sheets and it’s not even calling one number. @Support_Team1

I’m trying to make an outgoing call from my google sheets list.
