Expected Behavior

/**
 * @pattern ^(?!-)[A-Za-z0-9-]+([\-\.]{1}[a-z0-9]+)*\.[A-Za-z]{2,6}$ Should be valid site domain.
 */
export type Domain = string;

export type DomainRecord = Record<Domain, string>;

interface RequestBody {
  record: DomainRecord;
  siteDomain: Domain;
}

Current Behavior

siteDomain has regex @pattern enforced. record does not.

Possible Solution

Steps to Reproduce

1. Implement simple controller with above typing

import { Body, Controller, Post, Route, SuccessResponse } from 'tsoa';

/**
 * @pattern ^(?!-)[A-Za-z0-9-]+([\-\.]{1}[a-z0-9]+)*\.[A-Za-z]{2,6}$ Should be valid site domain.
 */
type Domain = string;

type DomainRecord = Record<Domain, string>;

interface ReproBody {
  record: DomainRecord;
  siteDomain: Domain;
}

@Route('/v0.1/repro')
export class ReproController extends Controller {
  @Post('/')
  @SuccessResponse('200')
  public async readPage(@Body() requestBody: ReproBody) {
    return requestBody;
  }
}

2. Send REST Client request and confirm validation error is as expected

POST {{url}}/v0.1/repro
Content-Type: application/json

{
  "record": { "https://some.domain.com": "test string" },
  "siteDomain": "https://some.domain.com"
}

3. Send REST Client request and see that validation error does not occur for record as expected

POST {{url}}/v0.1/repro
Content-Type: application/json

{
  "record": { "https://some.domain.com": "test string" },
  "siteDomain": "some.domain.com"
}
