I am trying to upload more than 7mb sized image which throwing before hit the server side action method '500 Internal Server Error' where below 7mb images are easily get uploaded.

below I am Serializing the file in angular to Base64 string.

$scope.UploadSysFiles = function (event){
      var file =;
      var reader = new FileReader();
      reader.onload = () => {
          $scope.SysFileByteCode = reader.result;
      $scope.SysFiles = file[0];

and storing all values in one object for sending to server side class object as below

$scope.SystemAccesories[rowIndex] = {};
    $scope.SystemAccesories[rowIndex].ManualFile = $scope.SysFileByteCode;
    $scope.SystemAccesories[rowIndex].FileName = $;
    $scope.SystemAccesories[rowIndex].FileSize = $scope.SysFiles.size;
    $scope.SystemAccesories[rowIndex].ContentType = $scope.SysFiles.type;
    $scope.SystemAccesories[rowIndex].IsManualFileAvailable = true;
now sending to server side like below

           method: 'POST',
           url: 'http://localhost:*****/Accesories/UpdateAccesories',
           data: { objSystemAccesories: $scope.SystemAccesories},
           headers: { 'content-type': 'application/json' }
         }).then(function (response) {
         //after get success, further steps

at backend I created one object class file and getting values in action method like below

public class SystemAccessories
     public string ManualFile { get; set; }
     public string FileName { get; set; }
     public string FileSize { get; set; }
     public string ContentType { get; set; }
     public Nullable<bool> IsManualFileAvailable{ get; set; }
    public ActionResult UpdateAccesories(SystemAccesories objSystemAccesories)
     //deserialize to byte array annd upload code

What I have tried:

I have updated the `web.config` file by below code

    <httpRuntime targetFramework="4.6.1" maxRequestLength="2147483647" executionTimeout="3600" requestLengthDiskThreshold="2147483647"/>   
            <requestLimits maxAllowedContentLength="2147483647"></requestLimits>
            <jsonSerialization maxJsonLength="50000000"/>

but still getting same issue, no change

Wow. People are still using Angular 1?

This has nothing to do with angular, it has to do with your server configuration
