fatal error in GraphQL Types

[RikvdHeijden]

Preconditions and environment

Version 2.4.5, don't know if other versions are currently affected

Steps to reproduce

Update your local composer and run di:compile.

Expected result

A successful di:compile

Actual result

The message will be something like: Fatal error: Type of Magento\Framework\GraphQl\Schema\Type\StringType::$name must be string (as in class GraphQL\Type\Definition\StringType)

Additional information

This is caused by an dependency of magento/framework: webonyx/graphql-php which created a BC incompatible version 14.11.7.

A temporary workaround is pinning the version to 14.11.6 in the root composer.json.

An issue has already been opened in the library: webonyx/graphql-php#1221

Can confirm, also ran into this problem on Magento 2.4.4

I came across this issue earlier doing updates to an existing site. This is caused by an update earlier today to composer module webonyx/graphql-php (https://github.com/webonyx/graphql-php)

I had to downgrade by running composer require webonyx/graphql-php:14.11.6

[Jarzebowsky]

I came across this one on Magento 2.4.5 as well. Temporary solution given by @chrisastley does the trick.

The original ticket has just been closed. This should work now.
