What is the current behavior?

Refine's GraphQL package is loosely based on nestjs-query. However, uses urql under the hood. urql uses 2 different types of error handling mechanisms, an errorExchange in exchanges or response.error on the result. The way refine is built using Tanstack query it is expecting an exception new Error to be thrown in order to be caught and treated as an error. But urql does not do this out of the box, and so refine always treats any error as a success, which impact the notifications provider.

What is the new behavior?

Once the error is received by client from the query or mutation, it passes the response.error to an error handler function that parses the error and throws it as Tanstack Query is expecting so that it is treated as an error and not as a success.

fixes (#6493): [BUG] @refinedev/graphql Error Handling does not work as it should

Notes for reviewers

• I have added in an error differentiator prefix. [Code], [Network], [GraphQL] so the error can be classified and handled accordingly, this may be a breaking change for anyone on the [Code] who has tightly coupled with the "Operation is required." is required string.
• Tests have been updated to validate the changes made.
• Documentation has been updated to add in sections for Handling errors based on the prefixes, managing retries and the Authentication has been updated as it was using the nestjs-query mechanism for a custom fetch instead of using the fetchOptions in urql.
• Thank you for allowing me to make this fix,
