你好，我正在尝试向以下端点发送post请求：

[HttpPost]
    [Route("/admin/plebs/decision")]
    public async Task<IActionResult> CreatePlebsDecisions(
        [FromBody] IEnumerable<CreatePlebsDecisionsRequest> decisionsRequest)

“CreatePlebsDecisionsRequest”看起来如下：

public record CreatePlebsDecisionsRequest
{
    public required string AdminId { get; set; }
    public required string PlebId { get; init; }
    public required bool IsAccepted { get; init; }
}

但是，当我发送这样的请求（通过Axios）时

// types
export type PlebsDecisionsRequests = {
  decisionsRequest: PlebDecision[];
};

export type PlebDecision = {
  plebId: string;
  isAccepted: boolean;
};
// calling code in component
const plebsDecisions = plebRequests.map((pr) => ({
      plebId: pr.plebId,
      isAccepted: pr.isAccepted,
    }));

    const request = {
      decisionsRequest: plebsDecisions,
    };
// the method itself
await makePlebsDecisions(request);
  const makePlebsDecisions = async (
    plebsDecisions: PlebsDecisionsRequests
  ): Promise<PlebRequestResponse> => {
    setIsLoading(true);

    const payload = JSON.stringify(plebsDecisions);

    try {
      const response = await axios.post('/admin/plebs/decision', payload);
// the post object in chome dev tools
{
    "decisionsRequest": [
        {
            "plebId": "8e694149-102c-4d23-9e43-3555b46b4c4b",
            "isAccepted": true
        }
    ]
}

我得到以下错误消息（来自API）：

{
    "$": [
        "The JSON value could not be converted to System.Collections.Generic.IEnumerable`1[DalaranApp.Contracts.Admins.Decisions.CreatePlebsDecisionsRequest]. Path: $ | LineNumber: 0 | BytePositionInLine: 1."
    ],
    "decisionsRequest": [
        "The decisionsRequest field is required."
    ]
}

我似乎找不到解决办法，有什么想法吗？
先谢谢你了
