Error in ssGSEA2(input.ds = opt$input.ds, output.prefix = opt$output.prefix, : object 'm' not found

Hi,
I'm using GenePattern for PTM-SEA analysis. However, the program is error. In stderr.txt file, there is a description of the error:

parsing as GCT v1.2
/opt/gpcloud/gp_home/users/guest_96259/uploads/tmp/run602331894243547394.tmp/input.data/1/pho_aml_try.gct 998 rows, 47 cols, 0 row descriptors, 0 col descriptors
Error in ssGSEA2(input.ds = opt$input.ds, output.prefix = opt$output.prefix, :
object 'm' not found
Execution halted

What is the reason for this?
Thank you for your attention!
