Save draft and submit for review returns Internal Server Error

[rossnorthrup]

Describe the bug

Workflow version: 1.5.7

When I login in and open a page and all the most recent revision content is there, on the Current page, I do not have to go up and choose the latest revision to see the content.

I make an edit.

I choose, in the upper right hand corner: “Create a Draft”. It now says: “Draft 1”, in the top grey tab where it used to say “Current”.

When I try to choose: “Save draft and submit for review”, I get an Internal Server error.

Steps to reproduce

1. Open an unpublished entry
2. Save draft and submit for review

Craft CMS version

3.9.3

Plugin version

Workflow 1.5.7 is a bit out of date now (3 years old), can you try on the latest version?
