Price API is not working. Receiving 500 error in Chapter 3 about twilio-and-sendgrid-python-course HOT 10 CLOSED

Thanks @TasosVellis I'll have a look and see what's going on. This service is run by Twilio so I have limited visibility but I'll figure it out.

Thank you for your time and effort @mikeckennedy . Awesome course by the way!

Hey @TasosVellis Glad you're enjoying the course. :)

I just tested the API and it works when called correctly. It seems like some parameter is missing and rather than doing the proper error handling, the API crashes. It should return status code 400 or 422 with a reason (like this value is missing or invalid).

Here's what you get when the Twilio Studio widget converts this to at GET call.

The response is:

{
  "total": 15.5
}

from twilio-and-sendgrid-python-course.

The problem appears for me when I test the flow in Whatsapp. If I try the api call through Postman,Chrome etc. Everything works as expected.

Hey. There very likely means that the specification in Twilio studio on the HTTP widget is wrong. Because it should be doing the same identical thing as calling it in Postman. Is it POST vs. GET? Some variable missing? Have a look.

That's funny, I switched it to a POST request in Twilio studio and it worked!In the course it is a GET

from twilio-and-sendgrid-python-course.

Hi @TasosVellis . Weird. I fiddled with this in the studio and it work. I even put it back to GET and it works. I wonder if something needed refreshing on the Twilio Studio side? I'm confused because it seems unchanged but there it is. I did change from http to https on the address but not sure it matters.

Hey @TasosVellis, apologies for dredging this back up, but I brought up this issue with our product team. In particular, it sounds like the WhatsApp API was throwing a 500 when you were missing some parameters. Can you give me some more insight about what was happening under the hood? What parameters were missing, and what endpoint were you trying to hit? Even better, if you have any SIDs for the errors you were getting, that'd be super helpful!

Thanks for looking into this @ayyrickay
