In middleware, how to catch exception and return custom error code with body
The following does work:
But, removing
setResponseStatus(422);
return { result: { error: "Validation error", status: 422 } } as any;
setResponseStatus(422);
return { result: { error: "Validation error", status: 422 } } as any;
as any results in TypeScript error
