Swagger - Invalid JSON errors - json

Question

I'm just starting with Swagger UI and I'm trying to understand how it works.
So far I've entered some JSON (manually) and this is the result:

}
}
}
}
}
}
However, swagger's validator says it's not valid. The error I get is this
[
{
"level": "error",
"domain": "validation",
"keyword": "anyOf",
"message": "instance failed to match at least one required schema among 2",
"schema": {
"loadingURI": "http://json-schema.org/draft-04/schema#",
"pointer": "/properties/type"
},
"instance": {
"pointer": "/definitions/Place/properties/lat/type"
}
}
]
Note that it works as expected (so far). It displays the data (models and models' structure) properly. Make requests and retrieves responses. Yet the validator says it's not valid. (The yellow badge saying 'Invalid', not the red one that says 'Error').
What am I missing?

Answer 1

Your spec is indeed not valid. In your Place definition, you use "type": "double" to describe the type of the lat (and also lng) property, but such a type does not exist.
If you want to describe a numeric value of 'double' size, you should change the definition as follows:
"lng": {
"type": "number",
"format": "double"
}
Do that everywhere you use the double type, and it should resolve that issue.
