Upgrade 1.7.9 -> 1.8.1 fails at step 103

I am running a non-docker version trying to upgrade from 1.7.9 to 1.8.1. Initially upgrade process was failing at step 90 which I found a workaround here, but after running the workaround sql query and restarting the upgrade process, it failed at step 103 with the following error:

If I proceed with skipping this step upgrade completes successfully and cms appears to be working - I can see media/layouts/etc. Should I be concerned about this error? If so - I rather go back to 1.7.9 and wait for resolution.

If you don’t have any more of those in the logs (perhaps truncate the logs and then watch them for a bit), then you should be OK to leave it.
