[galaxy-dev] broken-pipe error on NGS Fastq tools "clip"

I am trying to set up a local instance. When running Clip adapter sequences I get the following error: fastx_clipper: Invalid quality score value (char 'J' ord 74 quality value 41) on line 36 gzip: stdout: Broken pipe I'm stuck on where to try to trouble-shoot this. This is on groomed fastq data in my history. I have the same error on other datasets. Other tools (Bowtie, FastQC) work on this dataset. I'm confused why it is gzip (but I clearly don't understand how Galaxy stores the data). Thanks for any suggestions!
