funannotate update ERROR

[ChuanzhengWei]

Are you using the latest release?
YES, my version is 1.8.17

Describe the bug
I used BRAKER to obtain predicted gene models (without UTRs), and I want to update my GTF file using funannotate. After converting it to a GFF file, I used the following command and it did not indicate any issues with the GFF file. I am not sure if funannotate supports updating GTF files from BRAKER, or if there is an error in my script.

What command did you issue?

singularity exec funannotate.sif funannotate update \
  -f pilon.fasta.masked -g tmp2.gff3 --species "Sbicolor" \
  --trinity transcript.fa -o braker_utr.gff
