GraphQL returns enum key instead of value

[JohnnyLouweret]

version 3.2.13

I'm not sure if its a bug but it does look like one.

Our api-platform rest api returns the value of enums while the graphql side returns the keys. This seems very weird and no idea how to change it.

case ENGLISH = 'EN';

GET users/1
locale: 'en'

query getUser {
  user(id: "/users/1") {
    locale
  }
}

locale: 'ENGLISH'

This one looks like it is happening in webonyx/graphql-php here: https://github.com/webonyx/graphql-php/blob/ca9e6b31a9c9682e89dbf838a00ea7754e7ad0e2/src/Type/Definition/EnumType.php#L136

I was able to produce the desired output by changing:

        return $lookup[$value]->name;

… to:

        return $lookup[$value]->value;

An additional note on above. The correct value is stored in $value and passed along up until that point, so I am not sure why they are changing it there.

Digging deeper … from GraphQL's API Reference the GraphQLEnumType has this note:

Some leaf values of requests and input values are Enums. GraphQL serializes Enum values as strings, however internally Enums can be represented by any kind of type, often integers.

Note: If a value is not provided in a definition, the name of the enum value will be used as its internal value.
