I also got this error and attempted the following (none of which solved the problem):

  1. Re-downloaded the fastq files
  2. Changed the assembler to SKESA (also had zero contigs)
  3. Ran spades alone (failed)

It seems the problem is with the reads, because the error also includes that there are an unequal number of reads between the two fastq files (see printout below from spades--full file name redacted). This was one of 100 assemblies I was able to do successfully with shovill, so I don't think it's a problem with shovill, and the fact that SKESA gave the same result suggests it's not an issue with spades either.
