Github Actions hang on integration test

https://github.com/langchain-ai/react-agent/blob/6302bd7c41a7254964d1f81e7aa619959ac2e409/tests/integration_tests/test_graph.py#L8

Wondering if anyone else see their Github actions hanging at this integration tests? Mine does, but the test defined in this file passed and then just hung indefinitely. Removing `@unit` seems to allow Github to complete this step very quickly.
