Broad Exception Catch (ARCH6153)

Key ruby.logging.broad-rescue · Severity info · Category logging

Catching the most general exception type (Exception, StandardError) also masks unexpected, unrelated failures. This hides real problems.

Incorrect

def process(order)
  charge(order)
rescue Exception => e
  Rails.logger.error(e.message)
end

Correct

def process(order)
  charge(order)
rescue PaymentError, Net::TimeoutError => e
  Rails.logger.error("Payment failed: #{order.id}", exception: e)
end

Fix

Rescue only the specific exception types you can handle; use domain exceptions instead of Exception/StandardError.
