Issues with API

Dear all,
I’m not a coder, and I’d like to use mini-dalle API for my app which is created in bubble.io

It seems I insert all the data correctly, but still I have API response:

Raw response for the API
Status code 400
{“error”:“Task not found for this model”}

Kindly help me to figure out how to make it work, here is the screenshot of the interface:

Thank you!
