While it looks like it’s malformed json that BQ is complaining about, I see some stack overflow posts indicating it could be related to java and networking and headers. So maybe worth checking there’s not malformed json in the source somewhere, it may also be worth checking your auth setup and that it’s able to connect and run “test” when you configure the destination. or even some BQ access or firewall setting that’s causing it to return something different when data actually gets pushed in, from whatever it returns when the connection gets tested.
