Sceduled job page not loading due to missing assembly

Vote:
 

When we go into our CMS 12 admin interface and open up the scheduled jobs page, nothing shows on the page. Looking at the logs we see an exception saying it could not load file or assembly EPiServer.Forms.UI, which makes sense because we haven't used Forms in the past two years or so. But apparently, its scheduled jobs are still in the database somewhere. 

I have tried deleting these misbehaving by running the following code:

var baddies = _scheduledJobRepository.List().Where(x => x.AssemblyName.Contains("Forms", StringComparison.OrdinalIgnoreCase));

foreach (var scheduledJob in baddies)
{
    _scheduledJobRepository.Delete(scheduledJob.ID);
}

In the first run it matched two jobs to be deleted. Rerunning it will result in no matches. However, the error stubbornly remains the same.  I have restarted the app in case of caching.

While scouring this forum, I came across the thread (Cannot load content types or schedules jobs after upgrade to CSM) that describes something very similar. The content types page loads just fine for us. We have tried the mentioned SQL delete statements, but that also had no effect.

We have all packages up to date (12.7.0). Any help with this would be greatly appreciated. 

The exception we're getting:

When is your code run? 

Try runing your code on an earlier stage. ex at the same stage as you run Geta.NotFoundHandler.Infrastructure.Initialization.NotFoundHandlerMiddleware. Or use a Migrationstep.

I would start with checking the database. Is there any rows in tblScheduledItem matching that Forms assembly?

If so, first delete all rows matching that jobs ID from tblScheduledItemLog and then finally delete the job from tblScheduledItem.

There are no rows in either tblScheduledItem or in tblScheduledItemLog containing Forms. I did just found a sole record in tblPlugin for the Forms assembly, deleting that resolved the problem! At least locally it did. What's the best way to remove this record on our DXP environments, where we (at least me, a power user) don't have direct access to the databases?

You can contact support@optimizely.com and provide them with the SQL query you want executed on the production environment.

The reason you are still seeing the errors was because the Forms scheduled jobs were registered by PlugIn attributes, you will need to delete those as well. Look into tblPlugin table to see those, and use PlugInDB to delete them based on their id(s)

We contacted support to have these SQL statements executed against all our environments.  After this we've had no more errors.

-- Remove Episerver Forms plugin records
DELETE FROM tblPlugin
WHERE AssemblyName = 'EPiServer.Forms.UI'

-- Remove Episerver Forms scheduled jobs logs
DELETE FROM tblScheduledItemLog
WHERE fkScheduledItemId IN (SELECT pkid FROM tblScheduledItem WHERE AssemblyName = 'EPiServer.Forms.UI')

-- Remove Episerver Forms scheduled jobs
DELETE FROM tblScheduledItem
WHERE AssemblyName = 'EPiServer.Forms.UI'

-- Remove ancient and empty XForm data table
DROP TABLE tblXFormData

-- Remove unused property definition types from Episerver Forms, XForms, and three custom ones
DELETE FROM tblPropertyDefinitionType
WHERE  AssemblyName IN ('EPiServer.XForms', 'EPiServer.Forms.UI')
