module RubyLLM::AgUI::ErrorSanitizer

Turns an exception into a safe (message, code) pair for RUN_ERROR.

Upstream Rails examples put ‘e.message` straight into RUN_ERROR, which can leak prompts, request bodies, API keys and internal paths. This module never does that: it classifies the error by class and returns a fixed, public message. The raw exception goes to the host logger, if the host configured one, and nowhere else.

Constants

FALLBACK
MESSAGES: Ordered by specificity. The first ancestor of the error whose name is a key wins, so subclass relationships are respected without loading optional error classes eagerly.

Public Instance Methods

Returns the [message, code] pair for error, falling back to FALLBACK.

# File lib/ruby_llm/ag_ui/error_sanitizer.rb, line 59
def classify(error)
  names = error.class.ancestors.map(&:name).compact
  names.each do |name|
    entry = MESSAGES[name]
    return entry if entry
  end
  nil
end

sanitize(error) click to toggle source

Returns a [message, code] pair safe to put on the wire.

# File lib/ruby_llm/ag_ui/error_sanitizer.rb, line 53
def sanitize(error)
  match = classify(error)
  match || FALLBACK
end
