Intermittent "Error Couldn't get userBody" leads to blank canvas

Does anyone recognize this error from the console?
“Error Couldn’t get userBody”
I see it gets logged from here

Whenever I see that error message, the canvas is totally blank and unusable.
But it doesn’t happen all the time, sometimes if I reload and goto a different component it kicks back to life

hmm usually this means for whatever reason, the <PlasmicCanvasHost/> didn’t render… you might try adding some console logs on your /plasmic-host page to make sure that the page component is at least rendering <PlasmicCanvasHost/>
