Error adding member={member} to organization={organization_i

Error message

Error adding member={member} to organization={organization_id}: {e}

What it means

Catch-all around the membership creation (and surrounding user resolution) in add_member: any unexpected failure — Prisma constraint violation, DB outage, serialization bug — is wrapped into an HTTPException 400 carrying the member and organization id, so the caller knows which add operation failed.
