Error when typing in Atom/Nteract: "{Current Date/Time} Unhandled shell message: complete_request"

As the title says, any time I type in a Go file in Atom after running a line with gophernotes I get an error like this
`2018/04/07 11:17:46 Unhandled shell message: complete_request`

This shows up in the top-right as a bubble, like most messages in Atom. When I select "show debug messages" in the Hydrogen settings, and display the console, nothing of relevance shows up. The kernel seems to work, but those messages make it very difficult to actually write the code.
