check_strandedness error with how_are_we_stranded_here tool

Hello,

I am trying to check the strandedness of my RNAseq files using the how_are_we_stranded_here tool. But when I enter the command:

check_strandedness --gtf $RNA_HOME/refs/sacCer3.ncbiRefSeq.gtf --transcripts $RNA_HOME/refs/sacCer3_transcripts.fa --reads_1 $RNA_DATA_DIR/GS_UM_H_S19_L008_R1_001.fastq.gz --reads_2 $RNA_DATA_DIR/GS_UM_H_S19_L008_R2_001.fastq.gz

everything seems to process properly until it begins checking strandedness (see output below)
