I'm running Symfony 5.4.14 with jms/serializer-bundle 5.2.0 and jms/serializer 3.21.0.

I have this in Symfony's config.yaml:

jms_serializer:
    enum_support: true

I can't get any Enums to serialise:

[Error] Object of class HMRX\CoreBundle\Entity\ClinicPharmacistRelationshipTypeEnum could not be converted to string

Same problem, any temporary solutions?

I've just found simple solution :)

You need to add attribute or annotation with type for jms serializer, it doesn't work with property type. Working example:

` #[ORM\Column( type: Types::INTEGER, enumType: ProductType::class )]

[Type(ProductType::class)]

protected ProductType $type = ProductType::PRODUCT;

` where ProductType is an Enum. @CJDennis

Ahm. I see now - based on the doctrine annotation it is mapped to simple type. I will take a look of we can fix it.
