The issue is around the version of the azure module that is included with Mobile Services, in order to not break some things, an older version of the Azure module is installed while the current is 0.9.6. In order to get the latest version of the Azure module, please follow these steps:
- Turn on Script Source Control (this can be done from the Dashboard of your Mobile Service in the Azure portal).
- Clone the git repository created by turning on Script Source Control.
- Navigate into the Service folder of the directory of your local git repo.
- Run this command: npm install azure --save
- This will install the latest module locally as well as adjust your packages.json to make sure that version is pulled down when you push your changes.
- Push the changes (git add, git commit, git push) back to Azure.
You should then be able to execute the getBlob method.
