💡 What: Eagerly initiates the external ZimaOS sessions fetch at the start of the dashboard health API route, instead of sequentially waiting for local DB and filesystem tasks.
🎯 Why: Resolves a bottleneck where the external network call blocked the response unnecessarily, maximizing concurrent execution in the handler.
📊 Impact: Reduces total API response time for the dashboard poll.
🔬 Measurement: Verify tests pass and visually inspect dashboard load latency.

Code Review

This pull request optimizes the response time of the dashboard projects health API route by initiating the external fetch fetchZimaOSSessionsPayload concurrently at the start of the handler. Feedback suggests improving the error handling of this promise by returning a fallback payload object in the .catch() block instead of using a dummy catch handler, which avoids throwing an exception during the subsequent await.

const zimaosSessionPromise = fetchZimaOSSessionsPayload(email);
// Attach a dummy catch handler immediately to prevent UnhandledPromiseRejection
// if the fetch fails before we await it later in the final try/catch block.
zimaosSessionPromise.catch(() => {});

Instead of attaching a dummy .catch(() => {}) handler that does nothing, it is cleaner and more robust to catch the rejection and return a fallback ZimaOSSessionsPayloadResult object. This prevents await zimaosSessionPromise from throwing an exception later in the handler, allowing the error to be handled gracefully through the existing oc.ok and oc.error checks rather than relying on the outer try/catch block.

  const zimaosSessionPromise = fetchZimaOSSessionsPayload(email).catch((err) => ({
    ok: false,
    status: 500,
    data: null,
    error: err instanceof Error ? err.message : String(err),
    attempts: [],
  }));
