I'm trying to upgrade Craft from and I'm getting an error. I am updating via Composer and get the following error when I run the migration script after upgrading:

Unknown Property: Setting unknown property: verbb\supertable\fields\SuperTableField::propagationMethod

Migration: craft\migrations\m190913_152146_update_preview_targets

I received a similar error when I tried to run the save entries script from the CLI as recommended in the upgrade documentation.

- Resaving test (10554) ... error: Setting unknown property: verbb\supertable\fields\SuperTableField::propagationMethod

I'm running the upgrade on my local server via Valet. Restoring the database brings me back to the migration screen...

Any suggestions would be helpful.

On the chance that anyone is having this same issue, here is what I needed to do to fix the issue (based on help provided by Craft's Support -- many thanks to them):

The Super Table plugin was out of date. The admin panel didn't show the issue and a composer update didn't either. I had to manually update the composer.json file to reflect the current Super Table version, "verbb/super-table": "2.4.9". Then I was able to clear the composer cache and run an update. The migration then worked just fine.
