• Is it possible that the PartitionKey uses the pointer type, resulting in a json parsing error?

  
  package proto

type NetworkCookie struct { ...

// PartitionKey (experimental) (optional) Cookie partition key.
PartitionKey *NetworkCookiePartitionKey `json:"partitionKey,omitempty"` 

}

Colud you please show your browser type and version

It's because the latest cdp protocol has changed the data fields. If you upgrade your chrome to the latest version, the problem should be resolved. Or you can use a old version of rod to use the old protocol.

ok, thank you, it is indeed such a problem, but the field such as cdp can also be changed
