wekan: Error: title is required

Issue

Server Setup Information:

• Deployment Method(snap/sandstorm/mongodb bundle): Docker

• MongoDB Version: 3.2.19

Problem description: I am running wekan as docker container. Had 0.63 and now updated to 0.80. When starting the container, the following error occurs:

Downgrading the container to 0.75 fixes it and wekan runs normally. It seems as if an migration had not run here?
