> I get an R Session Error in RStudio Server when I try to read an empty .feather file.
> Error: The previous R session was abnormally terminated due to an unexpected crash. You may have lost workspace data as a result of this crash. 
> Reproduce:
>  * Create empty pandas dataframe in Python
>  * Write to .feather file with .reset_index(drop=True) and compression="uncompressed"
>  * Try to read data in RStudio with arrow::read_feather(path)
>  * Error
> I can read dataframes with one or more rows in RStudio.
> I can read the empty dataframe with pandas.read_feather(). This returns an empty pandas dataframe.
