Status codes

Code	Description
`400`	Bad request A request failed GraphQL validation or failed to be parsed.
`401`	Unauthorized Requests may receive this response in two cases: For a client request that requires authentication, the client's JWT failed verification. For a non-client subscription endpoint calling a subscription callback URL, the router couldn't find a matching subscription identifier between its registered subscriptions and a subscription event.
`405`	Method not allowed A request used an unallowed HTTP method. ⓘ NOTE Both mutations and subscriptions must use POST.
`406`	Not acceptable A request's HTTP `Accept` header didn't contain any of the router's supported mime-types: `application/json` `application/graphql-response+json` `multipart/mixed;deferSpec=20220824` `multipart/mixed;subscriptionSpec=1.0`.
`429`	Too many requests Request traffic exceeded configured rate limits. See client side traffic shaping.
`499`	Request canceled by client The request was canceled because the client closed the connection, possibly due to a client side timeout.
`500`	Internal server error The router encountered an unexpected issue. Report this possible bug to the router team.
`504`	Request timed out The request was not able to complete within a configured amount of time. See client side traffic shaping timeouts.

ⓘ NOTE

You can create Rhai scripts that throw custom status codes. See Terminating client requests to learn more.
