I followed the steps stopping all extensions, ignoring all other updates, then hitting update so that it only attempts the TI update.

In case it matters, this location was on v2 and i did migrate to v3.0.4-beta.20.1 with minor issues. To perform that migration i had to run the update/migration. It failed but it did migrate the database correctly(as far as i know) just not all the files. So I backed up the migrated database, made a new clean v3.0.4-beta.20.1 installation with no demo data or anything. Then since I had those files working and clean from a fresh installation I dropped all the database tables and imported my migrated database. All seems to work fine. Have had no errors in my system log at all for months except for 2 instances of this, but I process 20-30 orders daily so if there was a major issue I think it would probably be flooding my logs.

Anyways enough of the backstory, the current error from attempting the update from v3.0.4-beta.20.1 to beta.22.2 is this…
