Reproduce the blank Visual preview using the supplied Insomnia and macOS versions, then start with the console error showing Electron's guest view manager rejecting the generated data URL. Compare the Visual preview path with the working Source code and Raw Data views; done means the response renders in Visual preview without the invalid-URL or unhandled-rejection errors.
