Cast error at Repository.fromJson() #384

Description

@Whiterzi

The error occurs in version 9.12+:

This happens when using the webhook API and receiving a POST request from a GitHub webhook.

Cause: type 'String' is not a subtype of type 'Map<String, dynamic>' in type cast
#0      _$RepositoryFromJson (package:github/src/common/model/repos.g.dart:129:48)
#1      new Repository.fromJson (package:github/src/common/model/repos.dart:454:7)

The problematic code is here:

organization: json['organization'] == null
? null
: User.fromJson(json['organization'] as Map<String, dynamic>),

The data structure looks like this:

{
  "repository": {
    "id": 677211832,
    "node_id": "R_kgDOKF1uuA",
    "name": "orgREPO",
    "full_name": "whiterOrg/orgREPO",
    "private": true,
    "owner": {
      "name": "whiterOrg",
      "email": null
    },
    ...
    "html_url": "https://github.com/whiterOrg/orgREPO",
    "description": null,
    "fork": false,
    "master_branch": "main",
    "organization": "whiterOrg"
  }
}

The issue is that the field organization is a string in this payload, but the code attempts to cast it to a JSON object of type User.
