Stop react query from retry on 404

TLDR: I cannot get correct typing for the error, as the react query uses

unknown

unknown

unknown

unknown type for the error in retry function. They also reccomend to perform a runtime check for the error. I'm kinda stuck as I don't lnow how to retrieve the error code from the error in retry function.

Currently I'm trying to stop react query client (that's used by the tRPC internally) from retrying on 404 and 401 HTTP errors. I found this issue https://github.com/TanStack/query/discussions/372#discussioncomment-6023276 and adapted the answer to my needs:

const MAX_QUERY_RETRIES = 4;
const SKIPPED_HTTP_CODES = [401, 402, 403, 404];

export const reactQueryRetry = (failureCount: number, error: unknown) => {
  if (failureCount > MAX_QUERY_RETRIES) {
    return false;
  }

  if (
    error instanceof TRPCError &&
    SKIPPED_HTTP_CODES.includes(getHTTPStatusCodeFromError(trpcError))
  ) {
    return false;
  }

  return true;
};

const MAX_QUERY_RETRIES = 4;
const SKIPPED_HTTP_CODES = [401, 402, 403, 404];

export const reactQueryRetry = (failureCount: number, error: unknown) => {
  if (failureCount > MAX_QUERY_RETRIES) {
    return false;
  }

  if (
    error instanceof TRPCError &&
    SKIPPED_HTTP_CODES.includes(getHTTPStatusCodeFromError(trpcError))
  ) {
    return false;
  }

  return true;
};

const MAX_QUERY_RETRIES = 4;
const SKIPPED_HTTP_CODES = [401, 402, 403, 404];

export const reactQueryRetry = (failureCount: number, error: unknown) => {
  if (failureCount > MAX_QUERY_RETRIES) {
    return false;
  }

  if (
    error instanceof TRPCError &&
    SKIPPED_HTTP_CODES.includes(getHTTPStatusCodeFromError(trpcError))
  ) {
    return false;
  }

  return true;
};

const MAX_QUERY_RETRIES = 4;
const SKIPPED_HTTP_CODES = [401, 402, 403, 404];

export const reactQueryRetry = (failureCount: number, error: unknown) => {
  if (failureCount > MAX_QUERY_RETRIES) {
    return false;
  }

  if (
    error instanceof TRPCError &&
    SKIPPED_HTTP_CODES.includes(getHTTPStatusCodeFromError(trpcError))
  ) {
    return false;
  }

  return true;
};

However, after inspecting this further the error isn't an isntance of TRPCError, as its shape differs from the TRPC's error structure:

// https://trpc.io/docs/server/error-handling
const error: TRPCError = {
  name: 'TRPCError',
  code: 'BAD_REQUEST',
  message: '"password" must be at least 4 characters',
};

// https://trpc.io/docs/server/error-handling
const error: TRPCError = {
  name: 'TRPCError',
  code: 'BAD_REQUEST',
  message: '"password" must be at least 4 characters',
};

// https://trpc.io/docs/server/error-handling
const error: TRPCError = {
  name: 'TRPCError',
  code: 'BAD_REQUEST',
  message: '"password" must be at least 4 characters',
};

// https://trpc.io/docs/server/error-handling
const error: TRPCError = {
  name: 'TRPCError',
  code: 'BAD_REQUEST',
  message: '"password" must be at least 4 characters',
};

Error's shape:

{
   "meta":{
      "response":{}
   },
   "shape":{
      "message":"Quiz not found",
      "code":-32004,
      "data":{
         "code":"NOT_FOUND",
         "httpStatus":404,
         "stack":"removed",
         "path":"quiz.byId",
         "zodError":null
      }
   },
   "data":{
      "code":"NOT_FOUND",
      "httpStatus":404,
      "stack":"removed",
      "path":"quiz.byId",
      "zodError":null
   },
   "name":"TRPCClientError"
}

{
   "meta":{
      "response":{}
   },
   "shape":{
      "message":"Quiz not found",
      "code":-32004,
      "data":{
         "code":"NOT_FOUND",
         "httpStatus":404,
         "stack":"removed",
         "path":"quiz.byId",
         "zodError":null
      }
   },
   "data":{
      "code":"NOT_FOUND",
      "httpStatus":404,
      "stack":"removed",
      "path":"quiz.byId",
      "zodError":null
   },
   "name":"TRPCClientError"
}

{
   "meta":{
      "response":{}
   },
   "shape":{
      "message":"Quiz not found",
      "code":-32004,
      "data":{
         "code":"NOT_FOUND",
         "httpStatus":404,
         "stack":"removed",
         "path":"quiz.byId",
         "zodError":null
      }
   },
   "data":{
      "code":"NOT_FOUND",
      "httpStatus":404,
      "stack":"removed",
      "path":"quiz.byId",
      "zodError":null
   },
   "name":"TRPCClientError"
}

{
   "meta":{
      "response":{}
   },
   "shape":{
      "message":"Quiz not found",
      "code":-32004,
      "data":{
         "code":"NOT_FOUND",
         "httpStatus":404,
         "stack":"removed",
         "path":"quiz.byId",
         "zodError":null
      }
   },
   "data":{
      "code":"NOT_FOUND",
      "httpStatus":404,
      "stack":"removed",
      "path":"quiz.byId",
      "zodError":null
   },
   "name":"TRPCClientError"
}

So I tried tRPC helpers

const trpcError = getTRPCErrorFromUnknown(error)

const trpcError = getTRPCErrorFromUnknown(error)

const trpcError = getTRPCErrorFromUnknown(error)

const trpcError = getTRPCErrorFromUnknown(error) and then

getHTTPStatusCodeFromError(trpcError)

getHTTPStatusCodeFromError(trpcError)

getHTTPStatusCodeFromError(trpcError)

getHTTPStatusCodeFromError(trpcError) but the HTTP code returned by helper is 500 instead of 404 visible in JSON.
