Error finding organization membership for user_id={data.user

Error message

Error finding organization membership for user_id={data.user_id} in organization={data.organization_id}: {e}

What it means

While removing/updating a member, the lookup of the (user_id, organization_id) pair in the organization membership table threw — typically a Prisma/DB connectivity or query error, not a simple absence. The endpoint converts it into a 400 so the client sees which user/org pair could not be resolved.
