The Error saying that the response from server is not a valid JSON string. Can you try responseString instead of responseJSON like
错误表明来自服务器的响应不是有效的 JSON 字符串。你能试试 responseString 而不是 responseJSON 吗
Alamofire.request(urlAddress, method: requestMethod, parameters: params).responseString{ response in
debugPrint(response)
}
See the Xcode debugger output & change it according to your need.
查看 Xcode 调试器输出并根据需要更改它。

I got the same error and i fixed it when I added encoding : JSONEncoding.default in the HTTPHeader. It could also be that the response from the server is an invalid JSON. You could get in touch with the server team and check if the output is of the correct format.
我遇到了同样的错误，我在添加编码时修复了它：HTTPHeader 中的 JSONEncoding.default。也可能是来自服务器的响应是无效的 JSON。您可以与服务器团队联系并检查输出格式是否正确。

The size of the image is too much. The allowed memory size of 134,217,728 bytes is exceeded. You tried to allocate 48,771,073 bytes on function:
图片尺寸太大。超出了 134,217,728 字节的允许内存大小。您尝试在函数上分配 48,771,073 个字节：
imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
Instead of:
代替：
image = info[UIImagePickerControllerOriginalImage]
Use:
用：
image = info[UIImagePickerControllerEditedImage]
