Handles potential errors when retrieving the active repository

Addresses a scenario where the active repository cannot be retrieved,
which commonly occurs when the currently open file is not part of a
repository.
A try-catch block is added to gracefully handle this situation,
logging the error and setting the active repository to undefined.
