Hi,
We are still using v3 of the backend. Users of our application can upload and download data, with a binary blob that is stored using the file system of Backendless. Only users of a certain group have access to the folder.
I was using the binary blob upload mechanism, but I want to migrate to the multi-part upload to avoid the file size limit of 2 800 000 bytes.
I am using Qt as client framework and although it is not easy to debug the core headers and such that are generated, I am pretty confident the multi-part packages are setup correctly.
When I overwrite a file (I am always using the overwrite=true parameter), everything works correctly: the big file is uploaded and I can download it afterwards without problems. When I try to upload a new file though, I get the following error:
{"code":6009,"message":"Unable to upload file"}
Authentication should be setup correctly as it works both when overwriting a file or uploading a new file using the binary blob method. The multi-part formatting should be setup correctly as it works perfectly when overwriting a file.
How can I debug this? Thanks!
Kind regards,
Jeroen
