Swallowed Exception (ARCH3151)

Key typescript.logging.swallowed-exception · Severity warning · Category logging

A handler that catches an exception and silently discards it - returning null/false or ignoring it - hides the failure. This differs from a strictly empty block: there is a body, but the exception is lost.

Incorrect

function getUser(id: string): User | null {
  try {
    return repository.findById(id);
  } catch (err) {
    return null;
  }
}

Correct

function getUser(id: string): User | null {
  try {
    return repository.findById(id);
  } catch (err) {
    logger.error("failed to load user", { id, err });
    return null;
  }
}

Fix

Log the caught exception or rethrow it before returning a fallback value.
