Hi,

Thank you for contacting support and sharing details.

We tested Aspose.Storage APIs but unable to produce The specified version does not exist error. APIs are working fine at our end. Would you please confirm whether you are still experiencing this error?

Yes, the error has been thrown all day.

The offending code on our side is this:

        String storage = null;
        return storageApi.GetDownload(fileName, "null", storage).ResponseStream;

As you see from the log, the upload, import data and set cell value operations are successful.

Dear Ola Noss,

You are receiving The specified version does not exist error because you are passing null as String value to version parameter.

return storageApi.GetDownload(fileName, “null”, storage).ResponseStream;

Instead, you should pass null object to version parameter. API call should be like following

return storageApi.GetDownload(fileName, null, storage).ResponseStream;

Thank you for your help, that solution works.
Funny that the string “null” has been working for months, and started giving error yesterday.

Please note, in latest Aspose.Cells Cloud API we have introduced storage API methods within the API. Now, it does not need to use Aspose.Storage Cloud API anymore. Kindly check latest Aspose.Cells Cloud SDK for Java for more details and feel free to contact us for any further assistance in this regard.
