I have been predicting genomic island using IslandViewer4 batch upload option (HTTP API), I have followed the following command as they mentioned but doing the same, I end up with an error.

curl -X POST -H 'x-authtoken:cec7aae4-0189-89ff-9e50-b2a60ff8fef6' -Fref_accnum="NZ_CP009019.1" -Fgenome_file=Xanthomonas_sp_DAR33341.gbk -Fgenome_name="Xanthomonas_sp_DAR33341" -Femail_addr="kumar@gmail.com" -Fformat_type="GENBANK" http://www.pathogenomics.sfu.ca/islandviewer/rest/submit/

I have opened my terminal exactly where my all genome gbk file lies. Anyone, please help me to fix this issue.
