Summary

In this release we’ve enhanced Logger to format error stack traces for easier reading in non-production environments.

We also fixed a bug in the Event Handler AppSyncEventResolver that caused subscription events to be rejected incorrectly. The fix requires no changes on your part besides updating to the latest version.

⭐ A big thank you to Ours Privacy for becoming a public customer reference, and @ConnorKirk for their contributions!

Changes

Pretty print stack trace in dev mode

Docs

You can now pretty print error stack traces when dev mode is enabled via the POWERTOOLS_DEV environment variable. This makes it easier to troubleshoot issues during development.
