- 294391@main added support to relay BiDi commands into the browser with the inspector protocol method `Automation.processBidiMessage`. - While the proper command reply is sent by the browser as a separate `Automation.bidiMessageSent` inspector event, the call to `Automation.processBidiMessage` stores its callback to wait for eventual errors during the relay process (e.g. unknown methods). - In the case of a browser crash, `SessionHost::inspectorDisconnected` is called and flushes the pending callbacks with empty error payload. - At the same time, `SessionHost::relayBidiCommand` assumes a `"message"` field is always present. As such, it crashes in this empty error scenario. Patch incoming.
