Unable to use `@sinclair/typebox`

[0xMukesh]

Hey! I'm trying to use typebox along with fastify-now, but I'm facing errors while doing so.

1. I have installed and imported the @fastify/type-provider-typebox library

2. I have configured the type-provider which would be used globally

   const server = fastify({
     logger: process.env.NODE_ENV === "development",
   })
     .setValidatorCompiler(TypeBoxValidatorCompiler)
     .withTypeProvider<TypeBoxTypeProvider>();

3. I have imported @sinclair/typebox to my route file and added the schema via:

   POST.opts = {
     schema: {
       body: Type.Object({
         name: Type.String({
           description: "Name of the user",
         }),
         email: Type.String({
           description: "Email of the user",
         }),
       }),
       headers: Type.Object({
         authorization: Type.String({
           description: "Admin API key of CandyPay's public API",
         }),
       }),
     },
   };

   When I try to run the application, I face this error:

   FastifyError [Error]: Failed building the validation schema for POST: /api/v1/api-key, due to error TypeGuard: Invalid type

I never tried using it with @fastify/type-provider-typebox and @sinclair/typebox, so not sure what is the source of the error. Can you try wrapping your Type.Object with Type.Strict? so it will be:

POST.opts = {
  schema: {
    body: Type.Strict(Type.Object({
      name: Type.String({
        description: "Name of the user",
      }),
      email: Type.String({
        description: "Email of the user",
      }),
    })),
  },
};

@yonathan06 Have tried it out, still the same error

[0xMukesh]

Is there any kind of way to integrate other input-validation library such as zod to fastify-now?

[yonathan06]

not sure if that is a fastify-now issue, does your code work with a regular route using register() function?

Hey! I have figured out the issue, was a mistake from my side. Thanks for pointing me towards the solution 😄
