Date used by forecasting seems to be "frozen" - it is equal to the date of the last commit to the project in CI, or date of starting the koku/masu container in case of local testing. if these dates are not equal to today, api returns forecasts for past days. For example, today is 2021-01-04, thus api should return forecasts from 2021-01-04 to 2021-01-31. But since the last commit to the project was 17 days ago, forecasting uses 2020-12-22 as today and api returns forecasts from 2020-12-22 to 2020-12-31. Consequently, forecast is not displayed in UI as there are no forecasting data available for January.
