Hello 

I just wanted to let you know about this:

When I upload a file by HTML5 API I got an error using your Upload sample from here:

Failed to load resource: the server responded with a status of 400 ()

console error message:

code: 400

debug: undefined

kinveyRequestId: undefined

message: "An error occurred."

name: "KinveyError"

stack: "o@https://da189i1jfloii.cloudfront.net/js/kinvey-html5-sdk-3.11.2.min.js:8:20525…"

The file still will be uploaded!

I found out that your sample is not complete:

1. var metadata ={
2. _id: '<file-id>',
3. filename: '<filename>',
4. mimeType: '<mime-type>'
5. };

After I added "size: <filesize> to the metadata it worked without any errors. Maybe you want to adjust your sample.

Regards

Hello Pranav

Thank you for your answer. Umm, no, I didn't include 'Content-Type and 'X-Kinvey-Content-Type'. I can't find anything about those types from where I got the sample codes: here

If you let me know where I got information about those, i.e. how to implement them I can try it. Here is my related code doing the upload. It's a bigger project and not that easy to let it run over the console since I upload files that I have previously stored in an indexedDB. Furthermore I guess that the console does not reveal all errors that appears connecting from client.

// Get file from indexedDB to upload
dbReadFile(media.id)
    .then(function(dbFile) {
        // Conversion required: ArrayBuffer is deprecated in XMLHttpRequest.send(). Use ArrayBufferView instead.
        var fileContent = new DataView(dbFile.file);
        var metaData = {
            '_id': media.id,
            'gameid': 'GS',
            'filename': 'gs-' + media.id + '.' + media.extension,
            'mimeType': media.type,
            'size': media.size, // otherwise error (400)
            'type': media.type.substring(0, media.type.indexOf("/")).toLowerCase()
            // public: true
        };

        // Upload file
        var promise = Kinvey.Files.upload(fileContent, metaData)
            .then(function(file) {
                delete media.state;
            })
            .catch(function(error) {
                console.log (error);
            });
    });

I'm fine with that, it works. :o)
