AS 3.7.3: Error in span section. Job not submitted.
Autosubmit 3.7.3 is producing invalid span sections in the job headers. I guess it happens only when you don't declare a TASKS variable. Maybe this variable is mandatory now? In that case I think everybody should be aware and update their jobs.conf files.
The resulting span section is the following: #BSUB -R "span[ptile=None]"
:)
