Error during data reading -- 'merging intron data' step

[nurie05]

I was trying to use for first time Ballgown with data formatted with StringTie but it only returns this error even with the exampled ta set provided in the package.

Any suggestion on how to solve this issue?
I'm using R version 3.6.1

This is the error:

bg = ballgown(dataDir=data_directory, samplePattern='sample', meas='all')
