unhandled promise rejection

[BernardA]

I have a Gatsby app that is throwing the error below when building it for development ( did not test for production )

So in terminal I run: gatsby develop

Then the error below is thrown after queries are executed. It will output 3 times what appears to be the same error:

Thanks @emn178 but I left Gatsby long ago. I am closing this.
