❔ Troubleshooting JSON Mapping for POST Request to UserAsync Endpoint

I'm seeking guidance on formatting the JSON body for a POST request to the following API endpoint: API Signature: csharp

[HttpPost("CreateProjectUser")] 
public async Task<ActionResult> CreateProjectUserAsync(HikariUser projectUser, string userName)

[HttpPost("CreateProjectUser")] 
public async Task<ActionResult> CreateProjectUserAsync(HikariUser projectUser, string userName)

JSON Body (inputData):

{
    "projectUser": {
        "Username": "exampleProjectUser",
        "Email": "exampleProjectUser1@example.com",
        "Password": "Abc!123",
        "Role": "Contributor"
    },
    "userName": "AM" 
}

{
    "projectUser": {
        "Username": "exampleProjectUser",
        "Email": "exampleProjectUser1@example.com",
        "Password": "Abc!123",
        "Role": "Contributor"
    },
    "userName": "AM" 
}

The issue I'm encountering is that "userName": "AM" is being incorrectly mapped to HikariUser projectUser.Username, when it should be filling the *exampleProjectUser *field. Additionally, the other properties of HikariUser are not being correctly populated and are showing as null. I've already tried using [JsonPropertyName("")] attributes without success. Any guidance or solutions to ensure the correct mapping of JSON properties to the method parameters would be greatly appreciated.

 public class HikariUser
 {
     [JsonPropertyName("username")]
     public string UserName { get; set; }

     [JsonPropertyName("email")]
     public string Email { get; set; }

     [JsonPropertyName("password")]
     public string Password { get; set; }

     [JsonPropertyName("role")]
     public string Role { get; set; }
 }

 public class HikariUser
 {
     [JsonPropertyName("username")]
     public string UserName { get; set; }

     [JsonPropertyName("email")]
     public string Email { get; set; }

     [JsonPropertyName("password")]
     public string Password { get; set; }

     [JsonPropertyName("role")]
     public string Role { get; set; }
 }

The solution for this that i made was the following Changed the signature to following

public async Task<ActionResult> CreateProjectUserAsync(**[FromBody]** HikariUser projectUser, string name)

public async Task<ActionResult> CreateProjectUserAsync(**[FromBody]** HikariUser projectUser, string name)

And then i filled the string param wiht string query.

endpoint/CreateProjectUserAsync?name=**John**

endpoint/CreateProjectUserAsync?name=**John**

Yeah you need to tell the modelsbinder where to get the data from. If you want to get everything from the body, make a record that has a user and a username

public record CreateProjectUserRequest(HikariUser ProjectUser, string Username);

[HttpPost("CreateProjectUser")] 
public async Task<ActionResult> CreateProjectUserAsync(CreateProjectUserRequest request)

public record CreateProjectUserRequest(HikariUser ProjectUser, string Username);

[HttpPost("CreateProjectUser")] 
public async Task<ActionResult> CreateProjectUserAsync(CreateProjectUserRequest request)

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
