Unable to find OutcomeProficiency

Error message

Unable to find OutcomeProficiency

What it means

The deleteOutcomeProficiency mutation raises "Unable to find OutcomeProficiency" when OutcomeProficiency.active.find_by(id:) returns nil — no active record matches the parsed id, including soft-deleted proficiencies excluded by the active scope.

Solutions

1. Verify the id via an OutcomeProficiency GraphQL query before deleting
2. Confirm the record is active (workflow_state == active) in the DB
3. Use the correct relay global id for the environment you are hitting
4. Recreate the outcome proficiency if it was deleted unintentionally

Example fix

// before
record = OutcomeProficiency.active.find_by(id: record_id)
raise GraphQL::ExecutionError, "Unable to find OutcomeProficiency" if record.nil?
// after
record = OutcomeProficiency.active.find_by(id: record_id)
if record.nil?
  raise GraphQL::ExecutionError, "Unable to find OutcomeProficiency (id: #{record_id})"
end

const prof = await query(outcomeProficiency, { id });
if (!prof) throw new NotFound(id);

function hasProficiency(p) {
  return p?.data?.outcomeProficiency != null;
}

try {
  await client.mutate(DELETE_OUTCOME_PROFICIENCY, { id });
} catch (e) {
  if (e.message === "Unable to find OutcomeProficiency") {
    invalidateCache("outcomeProficiencies");
  } else throw e;
}

When it happens

Trigger: Calling deleteOutcomeProficiency with a nonexistent id, an already soft-deleted proficiency's id, or a malformed id that parses but matches nothing.

Common situations: Stale references after another admin deleted the proficiency scales, double-submitted mutations, or environments (test vs prod) with different data.

Understand the failure class

Background: "Not found" and "does not exist" errors: why "Task not found", "No such folder", and "Can't find" fire when a lookup comes back empty — this error's family across 14 libraries.
