Hi, I was trying to get the fasta for a BLAST result from the following database: http://brassicadb.cn/#/BLAST/ and received the following error message

Something went wonky

Looks like you have encountered a bug in SequenceServer. Could you please report this incident to your admin or to SequenceServer Google Group (if you are the admin), quoting the error message below?

Are you the admin of brassicadb.cn? Because this issue requires attention of the person who created/manages that website. If not, please forward this message to them.

You see this error because the protein databases you searched likely contain a * in the sequence to denote translation stop.

The options are,

1. Upgrade to SequenceServer 2.0 (https://groups.google.com/g/sequenceserver/c/c98ePBzcuVE/m/xy5opgAMBwAJ)

2. In /usr/local/share/gems/gems/sequenceserver-1.0.14/lib/sequenceserver/sequence.rb, look for the line

Sequence.new(*line.chomp.split(' '))

and add the following just above it:

line = line.encode('UTF-8', invalid: :replace, replace: 'X')

This will replace * characters with X in the output. SequenceServer 2.0 handles this error in the same manner.

3. Remove ‘*’ from the databases
