Grapqhl schema is empty [4.2.5]:

[vitalijalbu]

What happened?

Description

My graqhql schema is empty, also i created a new one but still empty.
Using craft pro 4.2.5, don't have a license key because still in development on a third-domain (https://demo.resthotels.it/)

Expected behavior

I came from version 3 where graphql worked fine, but now in version 4 cannot access to graphql. Maybe is due to the license key=?!
Would be better to add a option of a third-domain development env where users can test their websites, without completely buying the license.

Actual behavior

Graqhql schema is empty.

Same problem with a fresh install using composer create-project craftcms/craft

If I press play I get this error:

{
  "name": "PHP Compile Error",
  "message": "Type of craft\\gql\\types\\DateTime::$name must be string (as in class GraphQL\\Type\\Definition\\ScalarType)",
  "code": 64,
  "error": "Type of craft\\gql\\types\\DateTime::$name must be string (as in class GraphQL\\Type\\Definition\\ScalarType)",
  "exception": "yii\\base\\ErrorException",
  ....
}

Forcing webonyx/graphql-php at version 14.11.5 seems to fix the problem

[vitalijalbu]

yes, i think so because just saw they released new version of graphql, so what should i do? by myself or wait for craft team? @brandonkelly thanks.

Looks like webonyx/graphql-php 14.11.7 contained breaking changes that were intended for 15.0.0, and a fix for 14.x is imminent – webonyx/graphql-php#1221 (comment)

[brandonkelly]

Just released Craft 3.7.55.1 and 4.2.5.1, which mark webonyx/graphql-php 14.11.7 as a conflicting package/version, so they can’t be used together.
