Unexpected error while getting the method or property newBlob on object Utilities.

[Lichael Hipolito]

Hi Team,

Kindly help me on this. I was trying to fetch the array data of ar_fileData, ar_mimeType and ar_fileName on doPost(e) function but an error says "Unexpected error while getting the method or property newBlob on object Utilities."

JS Code:

document.getElementById('file'+<?=[i]?>).addEventListener('selectchange'+<?=[i]?>, function(e){

alert('selectchange'+<?=[i]?>);

var ar_file=[];

var ar_reader=[];

var ar_onload=[];

var ar_fileData=[];

var ar_mimeTypeStart=[];

var ar_mimeTypeEnd=[];

var ar_mimeType=[];

var ar_fileName=[];

for (var k=1; k<=2;k++)

{

ar_file[k]=event.targetfiles[0];

ar_reader[k]=new FileReader();

ar_reader[k].onload=function(e){

ar_fileData[k]=e.target.result.substr(e.target.result.indexOf(",")+1);

ar_mimeTypeStart[k]=e.target.result.indexOf("data:")+5;

ar_mimeTypeEnd[k]=e.target.result.indexOf(";");

ar_mimeType[k]=e.target.result.substr(ar_mimeTypeStart[k], ar_mimeTypeEnd[k] - ar_mimeTypeStart[k]);

ar_fileName[k]=ar_file[k].name;

document.getElementById('fileData'+<?=[i]?>).value =ar_fileData[k];

document.getElementById('mimeType'+<?=[i]?>).value =ar_mimeType[k];

document.getElementById('fileName'+<?=[i]?>).value =ar_fileName[k];

};

ar_reader[k].readAsDataURL(ar_file[k]);

}  

});

doPost(e) Code:

  var data = Utilities.base64Decode(e.parameters.ar_fileData);

  var blob = Utilities.newBlob(data, e.parameters.ar_mimeType, e.parameters.ar_fileName);

  var url1 = destination.createFile(blob);

  listRecord(e.parameter.checklist, e.parameter.upload1, e.parameter.comment1, e.parameters.ar_fileName, url1,);
