An Azure managed PostgreSQL database service for app development and deployment.
Hi @jw
Thanks for your question.
Based on Correlation ID you have shared, the deployment seems failed due to
The subnet with name ['GatewaySubnet'] in virtual network ['es-vnet'] is not allowed to host a Postgres flexible server. Please choose another subnet.

Hope this helps!
Let us know if you have any concern of need additional information.
Thank you!
