Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

Question

Hi,

I am getting an error as Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) while uploading a file in Document library via webpart by JSOM.

Below is the Code that I am using to upload file in chunks.

that.insertDocument = function (file, Id, docType, resolutionId, TicketNumber, handleLoader = true) {

// Generate a new GUID string

var newGuid = SP.Guid.newGuid().toString();

console.log(newGuid);

// Function to create a GUID string in the correct format

function createGuid() {

return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxx'.replace(/[xy]/g, function (c) {

var r = Math.random() * 16 | 0,

v = c == 'x' ? r : (r & 0x3 | 0x8);

return v.toString(16);

});

}

// Get the context and the SharePoint list where you want to upload the file

var clientContext = SP.ClientContext.get_current();

var web = clientContext.get_web();

clientContext.load(web, 'ServerRelativeUrl');

clientContext.executeQueryAsync(

async function () {

console.log

var folderServerRelativeUrl = web.get_serverRelativeUrl() + '/ArcilDocuments';

var docLib = web.getFolderByServerRelativeUrl(folderServerRelativeUrl);

console.log(folderServerRelativeUrl);

var chunkSize = 1024 * 1024;

//var fileInput = document.getElementById('fileInput');

//var file = fileInput.files[0];

//debugger

// Calculate the number of chunks

var fileSize = file.size;

var numChunks = Math.ceil(fileSize / chunkSize);

var fileName = file.name;

var names = fileName.split('.');

var ext = names.pop();

var newName = TicketNumber.replace(/\//g, '-') + '-' + names[0] + '-' + new Date().getTime() + '.' + ext;

console.log(newName);

// Create a new file creation information object

var fileCreateInfo = new SP.FileCreationInformation();

console.log("fileCreateInfo object:", fileCreateInfo);

fileCreateInfo.set_url(newName);

console.log("fileCreateInfo after set_url():", fileCreateInfo);

fileCreateInfo.set_overwrite(true);

console.log("fileCreateInfo after set_overwrite():", fileCreateInfo);

fileCreateInfo.set_content(new SP.Base64EncodedByteArray());

console.log("fileCreateInfo after set_content():", fileCreateInfo);

console.log(fileCreateInfo);

//debugger

// Upload the file to SharePoint

var newFile = docLib.get_files().add(fileCreateInfo);

var listItem = newFile.get_listItemAllFields();

listItem.set_item('Year', new Date().getFullYear());

listItem.set_item('TicketId', Id);

listItem.set_item('DocumentType', docType);

listItem.set_item('UploadedOn', new Date());

listItem.set_item('ResolutionId', resolutionId);

listItem.set_item('DocumentStatus', true);

listItem.update();

// Upload the file in chunks

var chunkIndex = 0;

var offset = 0;

var chunkReader = new FileReader();

chunkReader.onload = async function (evt) {

if (evt.target.error == null) {

var buffer = evt.target.result;

var endpoint = offset + buffer.byteLength - 1;

var chunkStream = new SP.Base64EncodedByteArray();

chunkStream.append(buffer);

var parameters = new SP.FileCreationInformation();

parameters.ContentStream = chunkStream;

parameters.FileName = newName;

parameters.Offset = offset;

parameters.OverwriteIfExists = true;

//debugger

// Start uploading the chunk

if (chunkIndex == 0) {

console.log(newGuid);

console.log("parameters object:", parameters);

// Start uploading the chunk

newFile.startUpload(parameters, newGuid);

console.log('Upload start');

} else {

//var chunkStream = new SP. Base64EncodedByteArray();

//chunkStream.append(buffer);

newFile.continueUpload(chunkStream);

console.log('upload continuously')

}

// Move to the next chunk or finish uploading

chunkIndex++;

offset += chunkSize;

if (offset < fileSize) {

readNextChunk();

} else {

newFile.finishUpload();

console.log('Upload completed');

clientContext.load(newFile);

await clientContext.executeQueryAsync(

function () {

var fileUrl = uploadedFile.get_serverRelativeUrl();

if (handleLoader == true) {

commonHelper.showHideLoader(false);

}

//console.log('File uploaded successfully - ' + fileUrl);

deferred.resolve(fileUrl);

},

function (sender, args) {

if (handleLoader == true) {

commonHelper.showHideLoader(false);

}

console.log('Error uploading file: ' + args.get_message());

deferred.resolve('');

}

);

}

}

}

var readNextChunk = function () {

var start = offset;

var end = Math.min(start + chunkSize, fileSize);

chunkReader.readAsArrayBuffer(file.slice(start, end));

};

readNextChunk();

})

};

Hi @Sagar Malde，This error message shows you create a wrong Guid format. You could use following code to create a 32 digits with 4 dashes guid

// Define a function named 'guid' that generates a unique identifier.
function guid(len) {
    // Initialize an empty array to store characters of the generated identifier.
    var buf = [],
        // Define a string containing all possible characters for the identifier.
        chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789',
        // Calculate the length of the character string.
        charlen = chars.length,
        // Set the desired length of the identifier or default to 32.
        length = len || 32;
    // Loop 'length' times to generate the identifier.
    for (var i = 0; i < length; i++) {
        // Generate a random index to pick a character from the character string.
        buf[i] = chars.charAt(Math.floor(Math.random() * charlen));
    }
    // Return the generated identifier by joining the array of characters into a string.
	var code = buf.join('');
	var fCode = code.substring(0, 8) + "-" + code.substring(8, 12) + "-" + code.substring(12, 16) 		+ "-" + code.substring(16, 20) + "-" + code.substring(20);

	return fCode;
}

Hi @Sagar Malde，

I'm glad to hear you solve the problem ,if you have any issue about SharePoint, you are welcome to raise a ticket in this forum.

By the way, since the Microsoft Q&A community has a policy that "The question author cannot accept their own answer. They can only accept answers by others." and according to the scenario introduced here: Answering your own questions on Microsoft Q&A, I would make a brief summary of this thread:

[Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)]

Issue Symptom:

Getting an error as Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) while uploading a file in Document library via webpart by JSOM.

Solution:

Passed the parameters incorrect. The startUpload method expects the first parameter to be GUID. The correct way of calling method should be newFile.startUpload(newGuid, offset, chunkStream);
