Still does not work. In the end I gave up choosing my own region because of AWS S3 bucket creation error present in logs. Now I tried using exact tutorial, no changes; Left Region EU WEST 1; Only change I did was to add Node version to 14.0.0 in package.json. Everything worked deployment wise but now I have a new error. This time in the AWS EBT hosted environment in node-red itself. When logging in I have a pop-up error that doesn't have a button to close it: notification.warnings.undefined
And Deploy button is disabled.
