Request failed for https://webhooks

[flutter-painter]

Hello @mrlynn,
Please could you help me sort this error when I run the script :

Request failed for https://webhooks.mongodb-stitch.com returned code 404 (line 68, file "Code")
Screenshots below.

Also I did not create any db in atlas, as in I did not define collections in mongo atlas, could it be linked with the error ?

Thank you for your time and for sharing this repo and tutorial, the video is very didactic
