Symfony 4: Doctrine ORM Mapping for PaymentToken not added in prod-Environment

[kije]

When using PayumBundle in Symfony 4 (flex), the Doctrine ORM mapping information for the PaymentToken Entity are not loaded when APP_ENV=prod.

This leads to an exception when trying to override the definition of the hash-Column (via @attributeOverride) to make it comaptible with utf8mb4_unicode_ci encoding (see Issue #319 ).
More information below.

The cause of this problem seems to be if there is a additional config/packages/prod/doctrine.yaml (as created by the default Symfony 4 setup) file with some additional configuration for Doctrine in the Production-Environment. The issue seems to be in the prepend()-Method of the Payum\Bundle\PayumBundle\DependencyInjection\PayumExtension class (see https://github.com/Payum/PayumBundle/blob/master/DependencyInjection/PayumExtension.php#L81 )

If I delete the file config/packages/prod/doctrine.yaml or when APP_ENV=dev, everything works fine.

Had the same issue, but found that the culprit, at least im my case, was the doctrine orm
auto_generate_proxy_classes: false setting in production mode.

Fixed it for now by setting auto_generate_proxy_classes: 2
