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?

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 ?
