Code Review
This pull request addresses an issue where a null server address could cause problems by adding exception handling around server address and port parsing. The changes are logical and include a new test case to cover the fix. My feedback focuses on refining the exception handling to be more specific, which improves the robustness of the code by not suppressing critical system errors.

In case of an invalid endpoint such as
localhost:-1, the current parsing logic returns null for server address. This PR made server address nullable. And added a null check for the port parsing.In addition, added a try catch for the whole parsing logic because serviceAddress and serverPort should only be used for obersevability and should not affect regular requests.
