I spent several hours hunting this bug in the Mautic code and when it didn’t go anywhere I found out that it’s caused by the Lead module being disabled by default. Enable it and it should get you going. Well, actually I’m adding more fixes to this plugin: [https://github.com/mautic/mautic/pull/4875](https://github.com/mautic/mautic/pull/4875). I also added this information to the docs.
