@vishnu-narayanan the action didn't capture the broken link https://www.chatwoot.com/hc/handbook/en/engineering/8 on https://www.chatwoot.com/docs/contributing-guide/ still

@sojan-official Looks like the action has some issues with recursive crawling. Let me see if there is another action that can accomplish that.
