    Description

      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.
