The resolved column is missing from the errors table. To enable resolve feature, run in Supabase SQL editor:
ALTER TABLE errors ADD COLUMN resolved boolean DEFAULT false;

The announcements table does not exist yet. Run the SQL migration first:
CREATE TABLE IF NOT EXISTS announcements (id uuid DEFAULT gen_random_uuid() PRIMARY KEY, message text NOT NULL, created_at timestamptz DEFAULT now(), created_by uuid, active boolean DEFAULT true);
ALTER TABLE announcements ENABLE ROW LEVEL SECURITY;
CREATE POLICY "Anyone can read announcements" ON announcements FOR SELECT USING (active = true);
