# Introduction We were allowing the sequence to be empty in the worker context that was facing an edge case importing the UpgradeModule through the WorkspaceModule god module, no commands were discovered and it was throwing as the sequence must have at least one workspace commands to allow a workspace creation Though the issue was also applicable to the twenty-server `AppModule` too that was not discovering any commands ## Integration tests were passing The integration test were importing the `CommandModule` at the nest testing app creating leading to asymmetric testing context It was a requirement for a legacy commands import and global assignation ## Fix The `UpgradeModule` now import both `WorkspaceCommandsProviderModule` and `InstanceCommandProviderModule` which ships the commands directly in the module We could consider moving the commands into the `engine/upgrade` folder ## Concern Bootstrap could become more and more long to load at both server and worker start When this becomes a problem we will have to only import the latest workspace command or whatever For the moment this is not worth it the risk to import not the latest workspace command

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
