Unable to access storage blobs without azureActiveContext

[davefrancis]

When calling azureListStorageBlobs(azureActiveContext = NULL, storageAccount = "accountname", container = "containername", storageKey = "storagekey") I get back the following error: Error: Provide a valid azureActiveContext. See createAzureContext().

When stepping through the function, I can see that the data is being returned by the API call.

Here is the traceback:

> traceback()
4: stop(assertError(attr(res, "msg")))
3: assert_that(is.azureActiveContext(x))
2: updateAzureActiveContext(azureActiveContext, storageAccount = storageAccount, 
       storageKey = storageKey)
1: azureListStorageBlobs(azureActiveContext = NULL, storageAccount = "accountname", 
       container = "containername", storageKey = "storagekey")
