成功的ajax请求进入错误回调而不是成功

Question

I have an AJAX request which aims at my API but the response goes in to the error callback instead of the success callback and I don't know why. The status response header is the success status (200). Can you help me please?

I can avoid this issue with the complete callback and if the status code is 200 or 400 I will display what I want, but it will not solve the real problem. It's actually what I did but it's not the best solution.

$.ajax({
  url: 'http://api.asaplace.v-labs.fr/users/me/cards/' + numCard,
  dataType: 'json',
  type: 'DELETE',
  headers: {
    'Authorization': 'Bearer ' + this.state.token
  },
  success: function() {
    console.log("success");
  },
  complete: function(xhr) {
    alert("carte supprimée avec succès");
    console.log("error");
  },
});

The request

我发现“dataType”是在 JSON 中的错误我把它放在 xml 中，它可以工作，谢谢大家的帮助
