51-51: Use ofmutatecan introduce race conditionsRetrieving the updated data with
mutate()while also callingsetSize()may cause overlapping requests if triggered multiple times in quick succession. Consider adding guards or checks to mitigate potential race conditions or unexpected state transitions.
114-115: ExtractPAGE_LIMITto a configurable constantDefining a magic number inside the component can limit flexibility if you need to adjust the page limit in the future. Consider placing
PAGE_LIMITin a config file or accepting it as a prop to make it more maintainable.

63-63: Simplified pagination callback looks goodThe concise arrow function for incrementing the page size via
setSizeis clean and straightforward. Good job.

💡 Codebase verification
🛠️ Refactor suggestion
Add error handling for pagination and data fetching operations
The code review concerns are valid. While the code handles basic error cases through SWR's error states, the pagination and mutation operations in the handleRunAll function lack proper error handling:
- The sequential
setSizeandmutatecalls are not wrapped in a try-catch block - The code continues execution even if
currentDatais undefined after mutation - There's no validation of the mutation response
Here are the specific locations that need attention:
apps/web/app/(app)/automation/ProcessRules.tsxlines 116-120:
let currentData = data;
if (!currentData?.[page]) {
await setSize((size) => size + 1);
currentData = await mutate();
}Should include error handling:
try {
let currentData = data;
if (!currentData?.[page]) {
await setSize((size) => size + 1);
currentData = await mutate();
if (!currentData?.[page]) {
throw new Error("Failed to fetch page data");
}
}
} catch (error) {
handleStop();
toastError({
title: "Error processing emails",
description: error.message
});
break;
}🔗 Analysis chain
Handle potential errors and concurrency issues when paginating
The loop for fetching additional pages based on PAGE_LIMIT works, but here are some considerations:
- Error handling: If
mutate()fails or returns an error, the loop continues. You may want to break early or handle the error to prevent reading fromundefineddata. - Concurrency: Double-check that
isRunningAllRefand the updates frommutate()don’t cause unexpected race conditions if a user manually triggers other pagination or runs the rules from a different flow. - Performance: Repeatedly calling
await onRun(message)for each message could be time-consuming for large pages. Consider parallelizing if your backend can handle it.
Based on the search results, I can see that setSize and mutate are part of the SWR (React Hooks for Data Fetching) library's API. The code follows the recommended patterns for pagination and data mutation:
setSizeis used to load the next page of datamutateis used to revalidate/refresh the data after changes- The code properly awaits both operations sequentially
Let's verify the error handling:
Let me fix the regex and try again:
Let me try a different approach to check the error handling:
