Commit 1: Updated packages and tried to fix the tests. Issue seems to be that when these tests run async that they hit the rate limit and so the connection fails. Code implementation as it is correctly requires async mode for invoke in code but not from deployed endpoint. Either need to fix this for local in code testing, or we find a way to limit number of async calls.

Commit 2: Removed async from test running and got them to run properly. Changed one of the test queries to one that passes. And reverted deepeval to 1.3.5 as 1.4.2 has a bug in it which means that context_relevancy test produces an error.
