I am getting an error with this javascript function definition in Azure. I am defining this within an Azure function for use by the exported function.

async function getData() {
    var data = await postRequest();
    return data;
};

Below is the error I am getting in the console. Is async await syntax not supported in Azure functions?

If yes, how would I implement an async call (such as a REST call made with node-rest-client).

For javascript async syntax support you need to install the latest version of the cli along side with node v8.x

npm i -g azure-functions-core-tools@core

Additionally you'll need to enable the beta runtime on azure so it also works when deploying.
