First things first, it looks like you are using a quite old version of the forest-express-sequelize.
Your should consider going to v5 → v6 → v7, especially because of this issue that will happen soon.
In any case, the issue might come from elsewhere though.
- Do you have an approximated date when you started to experience this issue?
- Do you use a specific link to access your app (Like a link from an email, etc…)? Or do you use the project list to access your project?
Thanks for your help
