A 404 error is a HTTP status code that indicates that the requested resource could not be found. This can happen for a variety of reasons, such as a typo in the URL, a deleted page, or a misconfigured server.
In GraphQL, 404 errors can be handled in a few different ways. One way is to use the errors field in the response. The errors field can be an array of error objects, each of which contains information about the error, such as the code, message, and path.
Another way to handle 404 errors in GraphQL is to use the notFound directive. The notFound directive can be used to specify a custom message that will be returned for 404 errors.
Finally, you can also use a GraphQL schema management tool like Squidex to handle 404 errors. Squidex can automatically generate 404 errors for resources that are not found, and it can also provide you with a way to customize the error message.
Here are the steps on how to handle 404 errors in GraphQL using Squidex:
- Install Squidex.
- Create a new GraphQL schema.
- Add the notFound directive to the field that you want to handle 404 errors for.
- Deploy your GraphQL schema to Squidex.
Once you have done these steps, Squidex will automatically generate 404 errors for resources that are not found. You can also customize the error message by editing the notFound directive.
