Validation failed: Payment source can't be blank

I have been struggling to locate what the actual issue is. I've tried tracing the problem but I am not getting enough information from the errors on where the issue is? Any help would be greatly appreciated as I am working on a production product.

When I run: bundle exec rake solidus_subscriptions:process

ActiveRecord::RecordInvalidsolidus_subscriptions:process
Validation failed: Payment source can't be blank

Tasks: TOP => solidus_subscriptions:process
(See full trace by running task with --trace)

Reproduce the failure with bundle exec rake solidus_subscriptions:process, then trace the call from lib/solidus_subscriptions/processor.rb to app/models/solidus_subscriptions/subscription.rb:201. Determine which subscription data leads to the missing payment source and define the expected behavior before adding a regression test; the issue is done when the task no longer fails for the reported case or reports a useful, tested error.
