This was at the time of the reply to the original post, around June 16th, 2022.
No SDK; just postman POST to the Data API endpoint.
The app region initially was the one it defaults to … I believe in our case that is AWS us-east-1 (same as the cluster location)
As far as not needing to change the deployment model, I disagree. It simply did not work (as per the post) when the deployment region was local instead of global.
It would be great to see cloud issues somewhere; this way, if anyone runs into a problem, you can at least see if it is a known issue.
Thank you.
