Description

Attempting to generate C# models for the Bungie API, using their openapi spec. Once generated and I deserialize the JSON, I get the following error: JSON integer 3612906877 is too large or small for an Int32

Upon investigation, the openapi file defines seasonHashes as

"seasonHashes": {
  "description": "...",
  "type": "array",
  "items": {
    "format": "uint32",
    "type": "integer"
  },
  "x-mapped-definition": {
    "$ref": "#/definitions/Destiny.Definitions.Seasons.DestinySeasonDefinition"
  }
}

Note the uint32. The generated code however, defines SeasonHashes as int, which is a smaller range of values, which does not fit the value coming from the API

// BungieNetApi\Model\DestinyEntitiesProfilesDestinyProfileComponent.cs
[DataMember(Name="seasonHashes", EmitDefaultValue=false)]
public List<int> SeasonHashes { get; set; }

If I manually change, in the generated C# code, these types to longs, everything works.

It appears the generator incorrectly generates uint32 types as int.

Suggest a fix

Start by running the provided openapi-generator command against the Bungie openapi-2.json spec, then inspect BungieNetApi\Model\DestinyEntitiesProfilesDestinyProfileComponent.cs. Trace the uint32 mapping in the csharp-netcore generator and verify that the generated SeasonHashes type can deserialize the reported value 3612906877 without an Int32 range error.
