+## 2024-03-07 - Automation StreamsLookup error handler

+The [Automation StreamsLookup error handler](/chainlink-automation/guides/streams-lookup-error-handler) is available to help you handle potential errors with StreamsLookup upkeeps. When you add the new [`checkErrorHandler`](/chainlink-automation/reference/automation-interfaces#checkerrorhandler-function) function, you can define custom logic to handle some errors offchain and handle other errors onchain in `performUpkeep`.
