In the newer version I had this introspection problem

[lucasantonioapto]

error: Introspection must provide input type for arguments, but received: [FlexibleFilter].

From the tests we did on the package in version: 8.6 this type works and in version: 9.1 it is not working and is returning this error.

I validated all my types and there is no error in defining types, everything is ok.

The upgrades of graphql-laravel often also include updates to webonyx-graphql, especially when we bumped the major to 9 we brought in a big update of webonyx and with it many improvement and strictness; so "tl;dr" I wouldn't be surprised that you now find issues not seen before.

That said, of course could be an issue in this library too 😅

Since you didn't provide much in terms of code to check, I may suggest a quick hack to use the webonyx built-in schema validator and see what it tells you.

In \Rebing\GraphQL\GraphQL::schema after this line:

$schema = $this->buildSchemaFromConfig($schemaConfig);

add

dd($schema->validate());

If it reports something, I suggest to look into that first.

If not … I would need more details to help.

ps: I was meant to add a console command to easily check this but never got around

Where would this line be: "\Rebing\GraphQL\GraphQL::schema"

I didn't find it in my project, and I did ctrl + shift + F in PHPStorm and didn't find anything

graphql-laravel/src/GraphQL.php

Line 66 in 05ca634

public function schema(?string $schemaName = null): Schema

I made this repository with the same real code I'm using, and it causes the same problem.

It already includes docker using mysql so you can run it without problems.

If you want to use types for "input", they need to extend Rebing\GraphQL\Support\InputType, see https://github.com/rebing/graphql-laravel#input-object .

In your project, FlexibleFilterType is a regular type.
