**Tech Triumph! Revolutionary Error Handling Enhancements Implemented in Reconciliation Process!**

**New fallback mechanisms to RPC ensure seamless operations amidst server timeouts, debunking inefficiencies in message handling!**

Commit Details:

Fix: Fallback to RPC in more cases when reconcile stream errors (#2396) ## Why is this change needed? In cases like this, we're not falling back to the RPC ``` {"jobName":"reconcile","jobId":"9273216","reason":"Unable to get all casts for FID 652934: server timeout","errorName":"Error","errorMessage":"Unable to get all casts for FID 652934: server timeout","errorStack":"Error: Unable to get all casts for FID 652934: server timeout\n at MessageReconciliation.getAllCastMessagesByFidInBatchesOf (file:///app/node_modules/@farcaster/shuttle/dist/index.mjs:1060:15)\n at runNextTicks (node:internal/process/task_queues:60:5)\n at process.processTimers (node:internal/timers:511:9)\n at async MessageReconciliation.allHubMessagesOfTypeForFid (file:///app/node_modules/@farcaster/shuttle/dist/index.mjs:980:22)\n at async MessageReconciliation.reconcileMessagesOfTypeForFid (file:///app/node_modules/@farcaster/shuttle/dist/index.mjs:918:22)\n at async MessageReconciliation.reconcileMessagesForFid (file:///app/node_modules/@farcaster/shuttle/dist/index.mjs:913:7)\n at App.reconcileFids (/app/src/shuttle.ts:132:13)\n at Worker.Worker.autorun (/app/src/worker.ts:21:9)\n at Worker.processJob (/app/node_modules/bullmq/src/classes/worker.ts:776:22)\n at Worker.retryIfFailed (/app/node_modules/bullmq/src/classes/worker.ts:982:16)"} ``` ## Merge Checklist _Choose all relevant options below by adding an `x` now or at any time before submitting for review_ - [x] PR title adheres to the [conventional commits](https://www.conventionalcommits.org/en/v1.0.0/) standard - [x] PR has a [changeset](https://github.com/farcasterxyz/hub-monorepo/blob/main/CONTRIBUTING.md#35-adding-changesets) - [x] PR has been tagged with a change label(s) (i.e. documentation, feature, bugfix, or chore) - [ ] PR includes [documentation](https://github.com/farcasterxyz/hub-monorepo/blob/main/CONTRIBUTING.md#32-writing-docs) if necessary. <!-- start pr-codex --> --- ## PR-Codex overview This PR focuses on improving error handling in the `reconcile` process by enhancing the fallback mechanism to RPC in more scenarios when stream errors occur, and temporarily skipping a test for unresponsive server requests. ### Detailed summary - Updated the `shuttle.integration.test.ts` file to skip the test for unresponsive server requests. - Enhanced the `messageReconciliation.ts` file to log a warning when a stream fetch times out and fall back to RPC. - Added a cancellation mechanism to prevent hanging connections. > ✨ Ask PR-Codex anything about this PR by commenting with `/codex {your question}` <!-- end pr-codex -->
