Error message

Claude Web browser interception target changed

What it means

Playwright route-interception guard in captureCompletion: a request matched the page.route() glob but failed the strict re-check (method POST plus exact /organizations/{org}/chat_conversations/{id}/completion path). It means the interceptor caught a request whose actual URL or method differs from the prepared conversation target — e.g. claude.ai issued a redirect or auxiliary API call that fell inside the route pattern.

Solutions

1. Tighten the page.route() pattern so only the exact completion endpoint is intercepted
2. Retry the turn: transient auxiliary requests during page warmup can hit the broad route; a fresh capture usually intercepts the right POST
3. If persistent, capture and log outgoing.url() to identify which claude.ai request is colliding
