No current goal

Error message

No current goal

What it means

GET /sessions/{session_id}/goal returns the current goal snapshot via get_current_snapshot(session_id); when no goal has been created (or the existing goal is no longer 'current', e.g. archived/completed) the route raises 404 'No current goal'. Note the session itself exists — the 404 is about the goal resource, not the session.

Solutions

  1. Create a goal first with POST /sessions/{id}/goal, then read it
  2. Treat 404 on this route as 'no goal yet' and show an empty state rather than an error
  3. Check goal lifecycle state — completed/archived goals may leave no current goal; create a new one
  4. Sequence client flows so goal read happens only after successful goal creation

Example fix

# before
snap = api.get_session_goal(sid)  # 404 for fresh sessions

# after
try:
    snap = api.get_session_goal(sid)
except NotFound:
    snap = api.create_session_goal(sid, objective="...", risk_tier="LOW_RISK")
Defensive patterns

Strategy: try-catch

Validate before calling

# know before you fetch: has a goal been created for this session?
r = client.get(f"/sessions/{sid}/goal")
has_goal = r.status_code == 200  # 404 means none set yet (session itself exists)

Try / catch

try:
    snapshot = api.get_session_goal(sid)
except NotFoundError:
    # 404 here means 'no current goal', not 'no session'
    snapshot = api.create_session_goal(sid, objective=default_objective, risk_tier="LOW_RISK")

Prevention

When it happens

Trigger: Calling GET /sessions/{id}/goal on a session that never had a goal set, or whose goal was replaced/archived so no current snapshot exists. The session id itself is valid (otherwise the session 404 fires first).

Common situations: Client fetches the goal immediately after creating a session but before creating a goal; UI showing a 'current goal' panel for goal-less sessions; flows where goal creation failed earlier and the error was swallowed; goal lifecycle moved it out of current state.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
