I found your bug report about the same error.
The job is likely failing for exceeding memory resources. A group of specific tools was problematic over the last few weeks, and a notice about reduced memory is in a banner at usegalaxy.org. Trinity is part of that group.
There are short reads in your inputs that will never assemble (what all the warnings are about) but that isn’t the root reason for the failure. Even smaller test runs failed over the weekend. We may need to update the banner again to state that Trinity is non-functional.
More details here, including workarounds: SPADES - Remote job server indicated a problem running or monitoring this job.
Thanks for reporting the problem!
