Commonly assumed
A CDPSession continues attempting raw protocol message dispatch when sent a command, even after its underlying connection is marked closed.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- In puppeteer 24.2.1 compared to 24.2.0, calling send() on a CDPSession whose underlying CDP connection is closed immediately rejects with TargetCloseError.
- In puppeteer 24.2.1, network request interception CDP errors containing Unsafe header are re-thrown by handleError rather than swallowed.
