I remember someone posted about this before but could not find it. For a given script, logs are not showing up, regardless of the log level selected. Pretty sure I am on the right script and that part of the script is being executed. Normally playing around with the "type" or the "view" does the trick, and after appearing blank for a while, they suddenly appear. But now they are not appearing at all. I have try deleting them all and triggering again the script but same result. Any suggestions?

I've seen a similar issue on some accounts back in September I believe. But then I couldn't get any logs on any script, or they were very delayed. Had to create a case to NS.

Well, it's around 2021.1 upgrade, so maybe is kind of related...

I had a similar issue in November or December. I couldn't find any reason for the logs to not log. I looked at the script a few days later and they were logging again with no change to the script! The only reasons I know of why logs would stop is because of Governance on Script Logging: https://system.netsuite.com/app/help/helpcenter.nl?fid=section_N3352137.html (we were way below this with only 2-3 logs per hour)
