Unable to open zip file after uploading model to Aida cloud

I’ve been uploading my models and when I download the file from the cloud after completing the upload process I get an error message when trying to open the zip file.

The error message is -

The model I up load is -

I believe I’ve named it correctly.

The file was previously a json file but changed to .aidax when renaming file.

Not sure what I’m doing wrong, I’m able to download and open other models on the cloud with no problem
