ActiveRecord connector error [MakaraMysql2RgeoAdapter]

[saurabhlime]

I was installing the gem in our project and got an error regarding a connector that we use "MakaraMysql2RgeoAdapter"
AppMap encountered an error inspecting a ActiveRecord::ConnectionAdapters::MakaraMysql2RgeoAdapter: undefined method `provide' for nil:NilClass
Sequel::Error (No database associated with Sequel::Model: have you called Sequel.connect or Sequel::Model.db= ?)

This error was thrown on a POSTMAN request of an endpoint. It works for certain Rspec test cases and does not for others.

Do you have a stack trace with file paths and line numbers?
