Unable to generate HAL from proxy

[alexmerlin]

Having an issue generating HAL response when a collection/entity contains proxies instead of their equivalent entities. I've found a discussion related to this here, but the provided solutions don't seem to fix the issue.
Is there a workaround for this?
We've made a fork in which at MetadataMap->__construct() we're pushing the entities to MetadataMap->$map to make sure that MetadataMap->has($class) looks for and finds the entities and not their proxies, but this does not seem to be the correct approach to the issue.
