Description

User got this error while running aws-s3-bulk-download.cwl with >6K input URLs, using a-c-r --submit --debug.

I don't think it actually interfered with the workflow's run at all, but it clogs the logs and looks scary.

IMO a-c-r (along with the rest of our code) should not try to log data that can be arbitrarily large.

Three instances where this came up:
