Description

The schemaController.compilersFactory.buildValidator property that can be passed to the Fastify-function is not of the same type as the return value of StandaloneValidator anymore.

Here is the error:

error TS2769: No overload matches this call.
  The last overload gave the following error.
    Type '{ (externalSchemas: { [key: string]: AnySchema | AnySchema[]; }, options?: { mode: "JTD"; customOptions?: JTDOptions | undefined; } | undefined): AjvCompile; (externalSchemas: { ...; }, options?: { ...; } | undefined): AjvCompile; }' is not assignable to type 'ValidatorCompiler | undefined'.
      Type '{ (externalSchemas: { [key: string]: AnySchema | AnySchema[]; }, options?: { mode: "JTD"; customOptions?: JTDOptions | undefined; } | undefined): AjvCompile; (externalSchemas: { ...; }, options?: { ...; } | undefined): AjvCompile; }' is not assignable to type 'AjvCompile'.
        Types of parameters 'externalSchemas' and 'schema' are incompatible.
          Type 'AnySchema' is not assignable to type '{ [key: string]: AnySchema | AnySchema[]; }'.
            Type 'boolean' is not assignable to type '{ [key: string]: AnySchema | AnySchema[]; }'.

56       buildValidator: factory,

Steps to Reproduce

Check out this code snippet from the readme:

const { StandaloneValidator } = require('@fastify/ajv-compiler')
const factory = StandaloneValidator({
  readMode: false,
  storeFunction (routeOpts, schemaValidationCode) {
    // routeOpts is like: { schema, method, url, httpPart }
    // schemaValidationCode is a string source code that is the compiled schema function
    const fileName = generateFileName(routeOpts)
    fs.writeFileSync(path.join(__dirname, fileName), schemaValidationCode)
  }
})

const app = fastify({
  jsonShorthand: false,
  schemaController: {
    compilersFactory: {
      buildValidator: factory // this does not compile anymore
    }
  }
})

Expected Behavior

It should compile.

I'm not a TS user so could you add a Minimal, Reproducible Example with the tsconfig and package.json details?

Here you go. Thanks for following up so fast.
