Genetic code 15. Failed validation of sequence '1'. Invalid characters were: ''''''''''''''''''''''''''

Hello prokka developers,

I am experimenting with different genetic codes for prophage sequences. I tried genetic code 4 and 11, works fine. Maybe for genetic code 4, I saw warnings like:

--------------------- WARNING ---------------------
MSG: Seq [subEli4]: Not using a valid terminator codon!
---------------------------------------------------

--------------------- WARNING ---------------------
MSG: Seq [subEli4]: Not using a valid initiator codon!
---------------------------------------------------

However, with the same sequence, on genetic code 15, I obtained the same warnings, with extra EXCEPTION:

------------- EXCEPTION -------------
MSG: Failed validation of sequence '1'. Invalid characters were: ''''''''''''''''''''''''''
