What is the current behavior?

Once you upgrade to v2.4.6 you will see errors like Cannot read properties of undefined (reading 'category') when Magento throws certain kinds of error.

Fixes: N/A

What is the new behavior?

In Magento versions that support GraphQl prior to v2.4.6 there was a key errors called "extensions" that contained an error code indicating what kind of error you received. For whatever reason, in v2.4.6 they removed this. This PR allows this extensions key to not exist when it used to always exist.
