In the BE we throw custom errors with precise error codes (e.g. "LABEL_ALREADY_EXISTS") before catching them in filters and rethrowing BaseGraphQLErrors (standard errors such as NotFoundError, UserInputError etc.). In the FE we were grouping sentries based on the error codes but we were actually grouping by very broad codes such as "NOT_FOUND" or "BAD_USER_INPUT", extracted from the BaseGraphQLErrors. To fix that, we update the BaseGraphQLError constructor api to allow to pass on the CustomError directly and retrieve from it the original code and store it in existing property `subCode` that we will use in the FE to send errors to sentry. This new api also eases usage of `userFriendlyMessage` that is passed on to the api response and therefore to the FE when CustomError is passed on directly to the BaseGraphQLError constructor.

Does the world need another CRM?
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.
