Description
Look into the log output snippet. It looks like there is an issue during aggregation when an unreadable file is encountered. Likely, this results in bad encoding.
LogType: command-13.json
LogLength: 13934
Log Contents:
Error aggregating log file.

Specifically, look at the text after the exception text. There should be two more entries for log files but none exist. This is likely due to the fact that command-13.json is expected to be of length 13934 but its is not as the file was never read.
I think, it should have been
