## What’s Changed

We have a couple fixes and some improvements to errors in this release.

### Fixes

- Fixed an issue where `read_state` polling requests would fail after the initial expiry, but before the request was processed
  - This was an edge case for subnets under high load. The `read_state` is allowed to use a fresh ingress\_expiry, so `pollForResponse` and `retry` logic now uses this pattern

- Added a check to handle a regression when calling the management canister using the new sync\_call flow

### Error handling

- Fixed an issue where `reject_code` and `reject_message` weren’t passed correctly to the error in synchronous call `reject` or `trap` responses.

- new `ActorCallError` class

- `AgentError` and `ActorCallError` support `instanceof` checks, as well as a `name` attribute that you can use for easier error handling
