format:Date and zipcode string in response example throws data mismatch error

[jsep925]

While parsing one document which have example in responses:

"responses": {
"200": {
"description": "Success",
"schema": {
"$ref": "#/definitions/ApiSuccessResponseAddressLookupResponseType"
},
"examples": {
"application/json": {
"meta": {
"app": "Vertex REST API v0.1.0",
"timeReceived": "2018-02-09T14:08:07.838Z",
"timeElapsed(ms)": 47
},
"data": {
"lookupResults": [
{
"jurisdictions": [
{
"jurisdictionLevel": "STATE",
"jurisdictionId": 31152,
"effectiveDate": "1900-01-01",
"expirationDate": "9999-12-31",
"value": "PENNSYLVANIA"
}
],
"postalAddresses": [
{
"streetAddress1": "2301 Renaissance Blvd Ste 7",
"city": "King Of Prussia",
"mainDivision": "PA",
"subDivision": "Montgomery",
"postalCode": "19406",
"country": "USA"
}
],
"statuses": [
{
"lookupResult": "NORMAL"
}
],
"taxAreaId": 390910000,
"asOfDate": "2017-12-18",
"confidenceIndicator": 100
}
]
}
}
}
}

With definition as following :
"effectiveDate": {
"format": "date",
"description": "The date when the tax for the jurisdiction became effective.",
"type": "string"
},
"postalCode": {
"description": "The postal code used to determine the Tax Area ID ",
"maxLength": 20,
"minLength": 1,
"type": "string"
},

I am getting following error in diagnostics:

Data and type mismatch found. [#/paths/1v11addresslookup/post/responses/200/content/application1json/example/data/lookupResults/0/jurisdictions/0/effectiveDate]
Data and type mismatch found. [#/paths/1v11addresslookup/post/responses/200/content/application1json/example/data/lookupResults/0/postalAddresses/0/postalCode]

For first error, GetSpecificOpenApiAny(IOpenApiAny openApiAny) in OpenApiAnyConverter didn't convert to type OpenApiDate, all date related string will convert to OpenApiDateTime, so it will marked as Data and type mismatch. Date format should also be supported.

For second error, the example postalCode only contain 5 digits, not full zip, It converted as OpenApiInteger. But since full zip contain 9 digit with "-", so definition as string is valid type, should it not auto convert to integer?
