1. Overview
1.1 Core Changes
- Primary purpose and scope: This PR addresses a critical bug in the
useChecksFetchhook where thetypeparameter is not sent from the frontend, causing the API to receive an "undefined" type. This fix ensures that thetypeparameter is correctly passed to the backend, preventing potential errors and ensuring accurate data retrieval. - Key components modified:
src/Pages/Uptime/Details/Hooks/useChecksFetch.jsx: Modified to acceptmonitorTypeand include it in the API call.src/Pages/Uptime/Details/index.jsx: Modified to passmonitorTypeto theuseChecksFetchhook.
- Cross-component impacts: This fix directly impacts the uptime monitoring feature by ensuring that checks are fetched correctly, which affects the accuracy of the visualizations and monitoring information displayed to users.
- Business value alignment: By resolving this bug, the PR enhances the reliability and robustness of the uptime monitoring feature, improving user trust and satisfaction.
2. Critical Findings
2.1 Must Fix (P0🔴)
[No critical issues found that must be addressed before merging]
2.2 Should Fix (P1🟡)
Issue: Lack of input validation in useChecksFetch for monitorType.
- Impact: Without validation, the hook might receive invalid or missing
monitorType, leading to unexpected behavior or errors. - Suggested Solution: Add input validation to ensure
monitorTypeis a non-empty string before making the API call.
Issue: Missing null checks for monitor and monitor.type in index.jsx.
- Impact: If
monitorormonitor.typeis missing, the application might not fetch checks correctly, leading to incomplete or incorrect data. - Suggested Solution: Add null checks and warning logs for
monitorandmonitor.typeto improve error handling and robustness.
2.3 Consider (P2🟢)
Area: Code maintainability and testing
- Improvement Opportunity: Add PropTypes to the
useChecksFetchhook for better type safety and maintainability. - Improvement Opportunity: Consider writing unit tests for the
useChecksFetchhook to ensure its long-term robustness and prevent regressions.
2.4 Summary of Action Items
- P1: Implement input validation and logging for
monitorTypeinuseChecksFetch.jsxand add null checks formonitorandmonitor.typeinindex.jsx. - P2: Add PropTypes to
useChecksFetchand consider unit tests for the hook.
3. Technical Analysis
3.1 Code Logic Analysis
📁 src/Pages/Uptime/Details/Hooks/useChecksFetch.jsx - useChecksFetch
- Submitted PR Code:
export const useChecksFetch = ({ monitorId, monitorType, dateRange, page, rowsPerPage }) => {
const [checks, setChecks] = useState(undefined);
const [checksCount, setChecksCount] = useState(undefined);
const [isLoading, setIsLoading] = useState(false);
const [networkError, setNetworkError] = useState(false);
useEffect(() => {
if (!monitorType) return;
const fetchChecks = async () => {
try {
setIsLoading(true);
const res = await networkService.getChecksByMonitor({
monitorId: monitorId,
type: monitorType,
sortOrder: "desc",
limit: null,
dateRange: dateRange,
filter: null,
page: page,
rowsPerPage: rowsPerPage,
});
setChecks(res.data.data.checks);
setChecksCount(res.data.data.checksCount);
} catch (error) {
setNetworkError(true);
createToast({ body: error.message });
} finally {
setIsLoading(false);
}
};
fetchChecks();
}, [monitorId, monitorType, dateRange, page, rowsPerPage]);
return [checks, checksCount, isLoading, networkError];
};- Analysis:
- Current logic and potential issues: The hook correctly accepts
monitorTypeand includes it in the API call. However, there is no input validation formonitorType, which could lead to errors if it is missing or invalid. - Edge cases and error handling: The hook returns early if
monitorTypeis missing, but this does not provide any feedback or logging. - Cross-component impact: The
monitorTypeparameter is crucial for fetching the correct checks data, affecting the accuracy of the uptime monitoring feature. - Business logic considerations: Ensuring
monitorTypeis correctly passed is essential for accurate data retrieval and user trust.

export const useChecksFetch = ({ monitorId, monitorType, dateRange, page, rowsPerPage }) => {
const [checks, setChecks] = useState(undefined);
const [checksCount, setChecksCount] = useState(undefined);
const [isLoading, setIsLoading] = useState(false);
const [networkError, setNetworkError] = useState(false);
useEffect(() => {
if (!monitorType || typeof monitorType !== 'string' || monitorType.trim() === '') {
console.warn("useChecksFetch: monitorType is missing or invalid. Skipping API call.", { monitorType });
return;
}
const fetchChecks = async () => {
try {
setIsLoading(true);
const res = await networkService.getChecksByMonitor({
monitorId: monitorId,
type: monitorType,
sortOrder: "desc",
limit: null,
dateRange: dateRange,
filter: null,
page: page,
rowsPerPage: rowsPerPage,

} finally {
setIsLoading(false);
}
};
fetchChecks();
}, [monitorId, monitorType, dateRange, page, rowsPerPage]);
return [checks, checksCount, isLoading, networkError];
};- Improvement rationale:
- Technical benefits: Input validation ensures the hook receives a valid
monitorType, preventing unexpected errors. Warning logs provide feedback and aid in debugging. - Business value: Ensures the uptime monitoring feature works reliably, improving user trust and satisfaction.
- Risk assessment: Minimal risk, as the changes are focused and well-justified.

const monitorType = monitor?.type;
const [checks, checksCount, checksAreLoading, checksNetworkError] = useChecksFetch({
monitorId,
monitorType,
dateRange,
page,
rowsPerPage,
});- Analysis:
- Current logic and potential issues: The code correctly extracts
monitorTypefrommonitor?.typeand passes it to theuseChecksFetchhook. However, there is no null check formonitorormonitor.type, which could lead to errors if they are missing. - Edge cases and error handling: The optional chaining operator prevents errors if
monitoris null or undefined, but it does not handle cases wheremonitor.typeis missing. - Cross-component impact: The
monitorTypeparameter is crucial for fetching the correct checks data, affecting the accuracy of the uptime monitoring feature. - Business logic considerations: Ensuring
monitorTypeis correctly passed is essential for accurate data retrieval and user trust.
- Current logic and potential issues: The code correctly extracts
- LlamaPReview Suggested Improvements:
let monitorType = monitor?.type;
if (!monitor) {
console.warn("Uptime Details: monitor object is not available. Checks might not be fetched.");
monitorType = undefined;
} else if (!monitor.type) {
console.warn("Uptime Details: monitor.type is not available in monitor object. Checks might not be fetched.", { monitor });
monitorType = undefined;
}
const [checks, checksCount, checksAreLoading, checksNetworkError] = useChecksFetch({
monitorId,
monitorType,
dateRange,
page,
rowsPerPage,
});- Improvement rationale:
- Technical benefits: Null checks for
monitorandmonitor.typeimprove error handling and robustness. Warning logs provide feedback and aid in debugging. - Business value: Ensures the uptime details page works reliably, improving user trust and satisfaction.
- Risk assessment: Minimal risk, as the changes are focused and well-justified.

3.2 Key Quality Aspects
- System scalability considerations: The changes do not impact system scalability, as they are focused on fixing a specific bug.
- Performance bottlenecks and optimizations: The changes do not introduce any performance bottlenecks or optimizations.
- Testing strategy and coverage: The PR does not include new tests. Consider adding unit tests for the
useChecksFetchhook to ensure its long-term robustness and prevent regressions. - Documentation needs: The changes are relatively small and focused. No significant documentation updates are required.
4. Overall Evaluation

Describe your changes
This PR addresses the issue of cases where the type parameter is not sent from the frontend. Currently, when type is not provided, it shows as undefined in the API, which can cause issues in processing.
