fix(weaver): improper exception handling

Address improper exception handling by wrapping expected exceptions in a
try-catch block and managing them explicitly.

Changes:

- Code is now enclosed within a try-catch to capture exceptions.
- Logs include contextual information for clarity.
- Exceptions re-thrown in getConfig() as part of propagation.
