tsed: [BUG] Body Validation not working as expected

Describe the bug

I’m currently migrating a express application to Ts.ED. I used joi for the validation before and currently try to make AJV work, as i like the direct support & swagger integration.

I have a problem making the following work:

import { Integer, Required } from '@tsed/schema';

export class Test {
  @Integer()
  @Required()
  value: number;
}

@Post('/some-url')
async someFunction(@BodyParams() body: Test) {
  ...
}

Also writing @BodyParams(Test) ... does not work.

I don’t find an exact documentation for this, except from Any model used on parameter and annotated with one of JsonSchema decorator will be validated with AJV. written here. So i guess my usage is correct and should work?

Also in my server.ts i have:

import '@tsed/ajv';

What does work for me is something like:

@Post('/some-url')
async someFunction(@BodyParams('value') @Integer() @Required value: number) {
  ...
}

but i would like to validate the whole body. Is this possible?

To Reproduce

Should be quite is to set up, see above.

Because this is also a kind of “should this be even possible” - issue, i dind’t create an extra reproducable repo. If you need one, let me know.

Expected behavior

I would expect the full body to be validated correctly when used as described above. The request should ail with the ajv error.
