Summary of Changes

Hello @tekrajchhetri, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses an issue where fetching community members failed due to an Unexpected end of JSON input error. It resolves this by enhancing the JSON parsing logic to gracefully handle malformed data and adds comprehensive logging to assist in diagnosing future data fetching problems.

Highlights

• Data Parsing Robustness: Enhanced the fetchCommunityMembers function in ui/lib/data.ts to include a try-catch block around JSON.parse calls, preventing crashes from malformed JSON lines and providing specific error messages for problematic data.
• Debugging Improvements: Integrated additional logging within fetchCommunityMembers to output details such as the raw response text length, a preview of the response, the total number of lines, and the content of the first line, which will be invaluable for debugging data integrity issues.

Code Review

This pull request attempts to fix an error when fetching community members by adding more robust JSONL parsing. However, the root cause of the issue is that the client is attempting to parse a single JSON object response as JSONL. The API already provides the transformed data, so the client-side transformation is also redundant. My review includes a critical comment with a suggested fix that correctly parses the API response and simplifies the function, removing the redundant logic.

[gemini-code-assist]

This change attempts to fix a JSON parsing error by adding more detailed error logging. However, the root cause of the error is a misunderstanding of the API response format.

The API endpoint /api/data returns a single JSON object, not a JSONL stream. Therefore, trying to parse it line-by-line will fail, leading to the SyntaxError.

Additionally, the API already performs the data transformation from raw knowledge graph entries to community members, including generating categories. The client-side transformation logic that follows this block is redundant and inefficient.

The correct approach is to parse the entire response as a single JSON object and use the data directly. This also has the benefit of removing the temporary console.log statements.

I suggest replacing this block with code that parses the JSON and returns the data. This will make the subsequent transformation code in this function redundant, and it should be removed.

Suggested change

	const text = await response.text();
	console.log('Response text length:', text.length);
	console.log('Response text preview:', text.substring(0, 200));
	const lines = text.trim().split('\n');
	console.log('Number of lines:', lines.length);
	console.log('First line:', lines[0]);
	// Parse JSONL data
	const kgData = lines.map(line => JSON.parse(line));
	const kgData = lines.map((line, index) => {
	try {
	return JSON.parse(line);
	} catch (error) {
	console.error(`Error parsing line ${index}:`, line, error);
	throw error;
	}
	});
	const data = await response.json();
	return { members: data.materials, categories: data.categories };
