scan_fasta_file.pl: unable to determine taxonomy ID for sequence

[amara86]

Hi,
I am trying to add genome of interest into my kraken database. The genome is not available on NCBI and I have downloaded it from somewhere else. The tax IDs for the genome are present in both nodes.dmp and names.dmp files but still kraken2 is not recognizing it. The genome sequence header are like this

Acropora_loripes_1
I tried
Acropora loripes 1
Acropora_loripes 1
but still getting the error
scan_fasta_file.pl: unable to determine taxonomy ID for sequence Acropora_loripes

Does the downloaded fasta file has taxid?
