Invalid model schema specified for swagger

问题

I tried to deploy API on AWS but it not allowed to add a model in the JSON file and shows error :

It working without the use of model so maybe it not take model this way so please suggest me how to use a model in API JSON on AWS!

Error is :

Your API was not imported due to errors in the Swagger file.
Unable to create model for 'LandingPageDTO': Invalid model specified: Validation Result: warnings : [], errors : [Invalid model schema specified]
Unable to put method 'POST' on resource at path '/userservice/la/program-summary': Invalid model name specified: null
Additionally, these warnings were found:
Reference to model 'LandingPageDTO' not found. Ignoring.

And my swagger json is :

{
  "swagger" : "2.0",
  "info" : {
    "description" : "demo",
    "version" : "v0.1",
    "title" : "demo"

          "additionalProperties" : {
            "type" : "string"
          }
        },
        "page" : {
          "type" : "integer",
          "format" : "int32"
        },
        "searchTerm" : {
          "type" : "string"
        },
        "size" : {
          "type" : "integer",
          "format" : "int32"
        },
        "sortDirection" : {
          "type" : "string",
          "enum" : [ "ASC", "DESC" ]
        },
        "sortProperty" : {
          "type" : "string"
        },
        "uid" : {
          "type" : "string"
        }
      },
      "example" : {
        "filter" : {
          "key" : "filter"
        },
        "uid" : "uid",
        "sortDirection" : "ASC",
        "searchTerm" : "searchTerm",
        "size" : 6,
        "sortProperty" : "sortProperty",
        "page" : 0
      }
    }
  }
}

Can any one suggest how to import model in swagger json api on AWS.

回答1:

According to AWS API Gateway - Known Issues:

• API Gateway supports most of the Swagger specification, with the following exceptions:
  • The additionalProperties field is not supported in Models.
  • The example tag is not supported.
  • Numbers of the int32 or int64 type is not supported.
  • ...

So it looks that your model is not fully compatible with API Gateway. Try removing additionalProperties, format: int32 and example from the model and see if it helps.
