Describe the bug

I have a Dash App running inside a Flask App. I am seeing a bunch of JS errors in the console after upgrading dash to 2.7.1. The Application renders a set of rows from a pandas dataframe containing Lat, Long on a mapbox map layer.

Expected behavior

The data must show on the map. It works as expected on dash v2.6.1.

This is the same as plotly/plotly.js#6444, correct?

[kevalshah90]

@alexcjohnson correct, they are related to plotly version upgrade to 2.7.1.

OK - let me close this one then, we'll continue the discussion in the plotly.js repo.
