Installing Redactor on Craft 3.1.2.1 errors

[CreateSean]

I updated a C2 site to C3. Added redactor via composer command and then installed via the plugin page and get this error.

Unknown Property – yii\base\UnknownPropertyException
Setting unknown property: craft\redactor\Field::availableAssetSources

The entire CP is unusable until I remove redactor from composer.json and run composer update

I fixed my issue by going through the tedious process of:

• removing redactor
• finding all redactor fields and changing to plain text (there were a lot)
• installing redactor
• finding all the changed fields and changing them back to redactor.

now everything works.

Not great, but I can move forward.

Also experiencing this exact problem. I'm updating a 5-year old site from Craft 2 to 3, and the idea of going through all of the Reactor fields, changing them to plain text, updating, and then changing them back would be quite a heavy lift.

Also, for mine, in order to get any usability back, I had to go into the DB and manually delete the redactor row from the plugins table.

Any hope for a solution for this?

My local setup is running on a Docker image. Craft 3.1.2.2 with a mysql DB.

Looking into this now.
