I have imported a swagger schema with which I want to validate my requests. Everything works very well. However, I am missing detailed information when the validation fails with **The response body didn’t match the specified schema** , which is not very helpful.

My idea was to perform an AJV validation in the post-response to get detailed errors. Is there a way to access the imported schema in this context? Or do I only have the option to redefine the schema at this point?

```auto
const body = pm.response.json();
const collectionPageSchema = pm.getCurrentResponseSchemaOrSomething(); ????

or

const collectionPageSchema = pm.api.definition.paths[...] ???

pm.test("Is valid JSON:API", function () {
    pm.expect(
        ajv.validate(collectionPageSchema, body),
        ajv.errorsText(ajv.errors)
    ).to.be.true;
});

```

Hi @tantchen81. Welcome to the Postman Community!

The schema defined within the API builder is not programmatically available in Postman scripts. You’ll have to store that schema as a variable or in the package library and validate it using Ajv. Additionally, [turning on request validation](https://learning.postman.com/docs/designing-and-developing-your-api/developing-an-api/validating-elements-against-schema/#enabling-request-validation) compares your response against the schema and gives you appropriate warnings on what may be wrong.

Tanks for reply @gbadebo-bello,

ok this was my fear. Of course the request validation is already on but not very helpful to debug the body schema.

Ah, I see. You’d have to store the schema separately to use it for a custom validation in your test scripts.

No, my hope was to get the schema programmatically from the already imported API builder an make a custom validation in a test-script. But it seems the solution is to repeat the schema in the test-script again.

This is no approach for me. Never repeat yourself in coding 😉

Hi @tantchen81. I totally understand this.

Would you mind raising this as a feature request [here](https://github.com/postmanlabs/postman-app-support/issues/new/choose) so we can look into some possibilities? I’d really appreciate you doing that.
