Two challenges with error messages - always provide a useful/meaningful error message for the end user instead of the generic one. eg: show "Wrong password" and not "An error occured" - avoid technical details unless error regards a technical feature. eg: show "An error occured" and not "Invalid post-hook payload."; but do show "Invalid issuer URL." as it occurs while configuring SSO What this PR does - Make userFriendlyMessage mandatory for widely used GraphqlQueryRunnerException and CommonQueryRunnerException, so that developers are forced to ask themselves what the error message should be, and as it contains very wide error codes (eg: "Bad request") which should not be mapped to just one default message - Keep userFriendlyMessage optional for service-specific exceptions (eg: workflowStepExecutorException), but convert the error code to userFriendlyMessage mapper to a switch case function with a typecheck ensuring that all codes are mapped to a message. These default messages are still overridable where they are thrown.

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.
