Hi,

Can you please share your app id (kid_xxxx)?

Also, are you able to do the first part of the upload process successfully? Are you getting successful response from Kinvey?

I am able to do the first part of the upload process successfully.Then i Get the upload url in the response.The problem is i am not able to upload image into the upload url,Might be i am missing some additional parameters.My App key is "kid_SyPxwgbI".

Hi,

If you are getting 201 success code back from Kinvey, then it seems to be an issue with the request going to GCS servers.

Have you gone through their documentation: https://cloud.google.com/storage/docs/xml-api/put-object-upload ?
