# Figma Advanced Troubleshooting

## Overview
Deep debugging techniques for complex Figma REST API issues that resist standard error handling: intermittent failures, unexpected response shapes, rate limit edge cases, and large file timeouts.

## Prerequisites
- Access to application logs
- `curl` with verbose mode for network inspection
- Figma API credentials for testing

## Instructions

### Step 1: Verbose Request Inspection
```bash
# Full HTTP request/response trace for a Figma API call
curl -v -H "X-Figma-Token: ${FIGMA_PAT}" \
  "https://api.figma.com/v1/files/${FIGMA_FILE_KEY}?depth=1" 2>&1 \
  | tee figma-debug-trace.txt

# Extract key diagnostic info:
# - TLS version and cipher
# - Response status and headers
# - Timing breakdown
curl -w "
DNS:        %{time_namelookup}s
Connect:    %{time_connect}s
TLS:        %{time_appconnect}s
TTFB:       %{time_starttransfer}s
Total:      %{time_total}s
Size:       %{size_download} bytes
Status:     %{http_code}
" -s -o /dev/null \
  -H "X-Figma-Token: ${FIGMA_PAT}" \
  "https://api.figma.com/v1/files/${FIGMA_FILE_KEY}?depth=1"
```

### Step 2: Response Shape Validation
```typescript
// Figma API responses can be unexpectedly shaped when:
// - File is empty or newly created
// - Nodes have been deleted between requests
// - Plugin data is corrupted

function validateFileResponse(data: any): string[] {
  const issues: string[] = [];

if (!data.document) issues.push('Missing document root');
  if (!data.document?.children?.length) issues.push('Document has no pages');
  if (typeof data.name !== 'string') issues.push('Missing file name');
  if (!data.version) issues.push('Missing version field');

// Check for null nodes (deleted between list and fetch)
  if (data.nodes) {
    for (const [id, node] of Object.entries(data.nodes)) {
      if (node === null) issues.push(`Null node: ${id} (deleted or invisible)`);
    }
  }

// Check images response for null renders
  if (data.images) {
    for (const [id, url] of Object.entries(data.images)) {
      if (url === null) issues.push(`Image render failed for node: ${id}`);
    }
  }

return issues;
}
```

### Step 3: Rate Limit Edge Cases
```typescript
// Problem: Figma rate limits are per-user, per-minute, but the exact
// limit is not published and varies by plan tier and seat type.

// Diagnostic: measure your actual limit by counting successful requests
async function measureRateLimit(token: string): Promise<{
  requestsMade: number;
  firstRateLimitAt: number | null;
  retryAfter: number | null;
}> {
  let count = 0;
  let rateLimitAt: number | null = null;
  let retryAfter: number | null = null;

// Make requests until rate limited (use a read-only endpoint)
  while (count < 200) {
    const res = await fetch('https://api.figma.com/v1/me', {
      headers: { 'X-Figma-Token': token },
    });

if (res.status === 429) {
      rateLimitAt = count;
      retryAfter = parseInt(res.headers.get('Retry-After') || '0');
      break;
    }

count++;
    // Small delay to avoid instant burst
    await new Promise(r => setTimeout(r, 100));
  }

return { requestsMade: count, firstRateLimitAt: rateLimitAt, retryAfter };
}
```

### Step 4: Large File Debugging
```typescript
// Large Figma files (1000+ components) can cause:
// - Response timeouts (>30s)
// - Memory issues (100+ MB JSON)
// - Rate limits from repeated retries

// Strategy: chunk the file by page
async function fetchLargeFileSafely(fileKey: string, token: string) {
  // 1. Get file metadata with depth=1 (just pages, not children)
  const meta = await fetch(
    `https://api.figma.com/v1/files/${fileKey}?depth=1`,
    { headers: { 'X-Figma-Token': token } }
  ).then(r => r.json());

console.log(`File: ${meta.name}, Pages: ${meta.document.children.length}`);

// 2. Fetch each page's content individually
  const results = [];
  for (const page of meta.document.children) {
    console.log(`Fetching page: ${page.name} (${page.id})`);

const pageData = await fetch(
      `https://api.figma.com/v1/files/${fileKey}/nodes?ids=${page.id}`,
      { headers: { 'X-Figma-Token': token } }
    ).then(r => r.json());

results.push({ pageId: page.id, pageName: page.name, data: pageData });

// Respect rate limits between page fetches
    await new Promise(r => setTimeout(r, 500));
  }

return results;
}
```

### Step 5: Support Escalation Template
```markdown
## Figma API Support Request

**Account email:** [your-email]
**Plan tier:** [Starter/Professional/Organization/Enterprise]
**Endpoint:** [e.g., GET /v1/files/:key]
**File key:** [file key, not sensitive]

### Issue Description
[1-2 sentences describing the problem]

### Reproduction Steps
1. Call `GET https://api.figma.com/v1/files/FILE_KEY?depth=1`
2. Observe: [expected vs actual behavior]

### Diagnostic Data
- HTTP status: [status code]
- Response headers: [relevant headers, especially rate limit]
- Response time: [from curl timing]
- Frequency: [every time / intermittent / specific conditions]

### Request/Response (redacted)
```
curl -v -H "X-Figma-Token: [REDACTED]" \
  "https://api.figma.com/v1/files/FILE_KEY?depth=1"

HTTP/2 [status]
x-figma-rate-limit-type: [value]
retry-after: [value]
```

### Environment
- Node.js: [version]
- OS: [os]
- Region: [your server region]
- Behind proxy: [yes/no]
```

## Output
- Verbose request/response traces captured
- Response shape issues identified
- Rate limit behavior measured
- Large file handled with page-level chunking
- Support ticket prepared with diagnostic data

## Error Handling
| Issue | Diagnostic | Solution |
|-------|-----------|----------|
| Intermittent 500s | Track frequency and timing | Log every request; report pattern to Figma |
| Slow responses | curl timing breakdown | Check if DNS/TLS is the bottleneck |
| Null image renders | Validate node visibility | Check node opacity and visibility in Figma |
| Memory crash | Large file JSON | Use `depth=1` + per-page `/nodes` calls |
