HTTPS REQUEST NODE ERROR: RESOURCE NOT FOUND!

Hey hi there, I'm trying to create an outbound calling agent with retell + n8n.

My workflow goes like this, it starts manual trigger, then it reads the data on google sheet (leads data like name, phone number etc...) then I add a loop node to send one data or one row data at a time, then I structure the data to send to https request node so that it can make the retell to do outbound call.

I have already correctly configured retell and twilio properly

My API key is also correct

My https request node URL is this: https://api.retellai.com/v2/create-phone-call
