Possibly missing requirement: symfony/config

[toitzi]

API Platform version(s) affected: 4.0.1

Description
This might not be the exact place to report this, as the error seems to come from the api-platform/graphql package (which doesn’t have an issue tab on GitHub). However, it appears to occur specifically within Laravel. If an invalid field type is encountered, the GraphQL package throws an InvalidTypeException in certain cases, such as here. The exception originates from the symfony/config package, which isn't required or included in a default Laravel installation, as far as I can tell. Hence, if this exception occurs, a PHP Fatal Error is thrown indicating that the class InvalidTypeException cannot be found.

How to reproduce
I haven’t pinpointed the exact cause yet, but it seems related to having an attribute in a model with an invalid or unsupported type in the type container.

Possible Solution
It might be necessary to include the symfony/config package as a dependency in the composer.json file. I’m not certain if this should be added here in the API Platform package or in the GraphQL package itself, but it seems more relevant to the latter.
