LEfSe Module B error


I am trying to run module B on http://galaxy.biobakery.org/ and I am getting this error. I’ve ignored this error and tried generating the LDA plot but it comes with an error message as well. Wondering if anyone else is having similar issues? I’ve listed the error I get in Module B

Error: Cannot count lines in dataset
