I FOLLOWED THE OFFICIAL AWS AMPLIFY GUIDE AND WAS CHARGED $1,100

Summary from the TLDR Web Dev newsletter

This developer was hit with unexpectedly high AWS charges after following the official guide for integrating Amazon OpenSearch with AWS Amplify. He was charged over $1,100 due to the guide's failure to properly manage OpenSearch domain creation and deletion, which led to multiple, concurrently running instances. AWS customer support ultimately waived the charges but the issue persisted until AWS recently fixed its docs.
