Invalid format in data for 5 counties of CA

[droantree]

When running the script for California, I found that the code expected to convert the timeseries JSON element into a dataframe but for 5 of the counties the timeseries element is empty and so the code fails. These counties are:
'06003', '06063', '06105', '06091', '06049'

Note: The actual error message I got was that mutate failed on as.Date. No surprise since it was trying to act on the "date" column and there was no such column!

P.S. It failed getting the OBSERVED intervention. The strong and weak intervention data might be OK.
