react-map-gl-geocoder: viewport-mercator-project: assertion failed.

After click on a result from the geocoder, I’m getting this error:

assert.js:3 Uncaught Error: viewport-mercator-project: assertion failed.

And the whole screen is turning white.

Good news is that your demo code works fine on my environment… so I guess I’ll start replacing stuff line by line until I find the culprit…

I’ll let you know what I find, and thanks again for your help

That is because your latitude and longitude are incorrect. So it is not a real place you have set.
