Looks like your website has a bug - try entering a house number which is non integer (Like say B-123) Submission fails with error: ``` {"statusCode":400,"error":"Bad Request","message":"ValidationError","data":{"errors":{"houseNumber":["houseNumber must be a `number` type, but the final value was: `NaN` (cast from the value `\"B-123\"`)."]}}} ```
It's wrong to assume that a house number is always an integer. My address has an alphanumeric house number. I have been in apartments without a house number (Instead they may have an alphabetical name. Something like XYZ House)
