Incorrect generated types for allow modifier

[wangshijun]

The joi schema:

const ChainInfo = Joi.object({
  id: Joi.string().optional(),
  host: Joi.string()
    .uri({ scheme: ['http', 'https'] })
    .required()
    .allow('none'),
})
  .options(options)
  .meta({ unknownType: 'string', className: 'ChainInfoType' });

The generated type:

export interface ChainInfoType {
  host: 'none';
  id?: string;
}

Expected type:

export interface ChainInfoType {
  host: 'string';
  id?: string;
}
