history not working on any NCM jobs

Yep, I'm seeing the same issue. The maximum size for the history seems to have gotten really, really small after the last update. I'm seeing this happen with anything that's more than about 30 or 40 lines. On the bright side, the emailed results are still working regardless of the size. 

Are you seeing it from the Jobs list (/Orion/NCM/Resources/Jobs/JobsList.aspx) page?

When I click on the history icon  I'm getting a modal box with the logs.

Then if I click save, the file seems to download fine.

I'm running Orion Platform 2020.2.6 HF1 with NCM 2020.2.6.

If you are still having problems, I'd definitely open a support case.

Running into this issue myself. At the bottom of the Jobs web page it just says "There was an error processing the request" and the loading box will spin indefinitely. This is keeping me from clearing the log also to see if it's just a size issue post upgrade to 2020.2.6 HF1

First off - this sounds like a bug and should be reported to support if you haven't already done so.

Secondly, I wrote something that uses the API to pull these history logs and (optionally) clears the logs.

If you'd like to try it, you are welcome to see if dumping and then clearing the logs fixes the problem.  As with all scripts, make sure you understand what it's doing and then make a backup of your system and database before running (to just be safe).

It was tested on Orion Platform 2020.2.6 HF1 and NCM 2020.2.6.

We have received your support request for support case #00903155.

Case open, lets see if anyone can figure it out.

Just tried out that script and it's getting an error around JobLogIndicator when it's trying to populate the $NcmJobs variable.

Get-SwisData : Cannot resolve property JobLogIndicator

Huh - I've got that field with Orion Platform 2020.2.6 HF1 and NCM 2020.2.6.  I don't know what to tell you if that field is missing.  I guess you could try and comment it out or remove it, but I used that field to determine if there was a log or not.
