Upgrading to V2 Scheduler Error

Anki Help

When I try to update to the V2 scheduler, I get this error:

Error
An error occurred. Please use Tools > Check Database to see if that fixes the problem.
If problems persist, please report the problem on our support site. Please copy and paste the information below into your report.
Anki 2.1.65 (aa9a734f) Python 3.9.15 Qt 6.4.3 PyQt 6.4.0

anki.errors.DBError: DbError { info: “InvalidColumnType(10, "factor", Real)”, kind: Other }

I did try “check database” and “check media” and nothing resolved the error.

Possibly noteworthy is the fact I haven’t used Anki desktop in a long time; I’ve been using Ankidroid every day, but it asked me to update to V2 also and is giving me a similar error.

When I entered the code into the debug console, I got the following:

>>> mw.col.db.execute("update cards set factor=round(factor)")
... mw.col.modSchema(False)
<string>:2:modSchema is deprecated: please use 'mod_schema'

But it still fully solved my issue. Ankidroid works again too. Thanks so much!
