Blank output When converting GFF3 file to GTF using either gffread or AGAT

Hi,

I am trying to convert gff3 file (please see below) to GTF. I used two tools suggested here gffread and agat here.

#gff-version 3

I was using following commands;
AGAT-

agat_convert_sp_gff2gtf.pl --gff genes.gff -o genes.gtf

gffread-

gffread -E -F -O -T genes.gff -o genes.gtf

Both giving me an empty output (AGAT just retrive # comment).
Can someone help me in this regard?
Thank you!
