Unable to Use ERD Gem with Solidus Due to "undefined method `preference' for..."

[pacarvalho]

When attempting to use the rails-erd gem to generate database relationship diagrams I get the following error in an application using Solidus:

➜  git:(master) ✗ bundle exec rails db:migrate
I, [2020-07-27T12:13:50.730310 #55190]  INFO -- sentry: ** [Raven] Raven 2.13.0 configured not to capture errors: Not configured to send/capture in environment 'default'

(See full trace by running task with --trace)

Has anyone experienced this problem before? There is no occurrence of the attribute preference in my code. I am currently going over the Solidus code but there are 79 occurrences of this attribute. Since the error message is not revealing the class name it has become a bit lengthy to debug this issue.

Solidus Version:
2.10.1

Desktop:
OSX 10.15.5

Can you please run it with --trace to reveal where this is called from?

Not sure how that's possible but it seems like it's trying to load Spree::BillingIntegration model before Spree::PaymentMethod that inherits from Spree::Base the preference method is defined. I'm almost sure that if you fork Solidus and try to manually require 'spree/payment_method inside Spree::BillingIntegration it should fix this issue. Let me know.
