I installed the development version from GitHub and tried to forecast a time series using 'auto.rima' for intermittent demand forecasting. But I got the following error.

Here is my testing example. test_ts.csv.zip

Oh I realized the testing time series data frame is a tsibble object. I have to convert to tibble object and then it works.

Yes, you'll need to work exclusively with data.frame or tibble objects. tsibble have different properties making it difficult to predict how they will respond to the modeltime workflow.
