# Canva Debug Bundle

## Overview

Collect diagnostic information for Canva Connect API issues. Tests connectivity to `api.canva.com/rest/v1/*`, validates OAuth tokens, checks rate limits, and packages evidence for support tickets.

## Instructions

### Step 1: Connectivity & Auth Check Script

```bash
#!/bin/bash
# canva-debug.sh — Run with: bash canva-debug.sh
set -euo pipefail

TOKEN="${CANVA_ACCESS_TOKEN:-}"
BUNDLE="canva-debug-$(date +%Y%m%d-%H%M%S)"
mkdir -p "$BUNDLE"

echo "=== Canva Connect API Debug Bundle ===" | tee "$BUNDLE/summary.txt"
echo "Generated: $(date -u +%Y-%m-%dT%H:%M:%SZ)" | tee -a "$BUNDLE/summary.txt"
echo "" >> "$BUNDLE/summary.txt"

# 1. Check API reachability
echo "--- API Connectivity ---" >> "$BUNDLE/summary.txt"
HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" \
  -H "Authorization: Bearer ${TOKEN}" \
  "https://api.canva.com/rest/v1/users/me")
echo "GET /v1/users/me: HTTP $HTTP_CODE" | tee -a "$BUNDLE/summary.txt"

# 2. Get user identity (if token valid)
if [ "$HTTP_CODE" = "200" ]; then
  curl -s -H "Authorization: Bearer $TOKEN" \
    "https://api.canva.com/rest/v1/users/me" | tee "$BUNDLE/user-identity.json" \
    | python3 -m json.tool 2>/dev/null || true
  echo "Token: VALID" >> "$BUNDLE/summary.txt"
else
  echo "Token: INVALID or EXPIRED (HTTP $HTTP_CODE)" >> "$BUNDLE/summary.txt"
fi

# 3. Check response headers for rate limit info
echo "" >> "$BUNDLE/summary.txt"
echo "--- Rate Limit Headers ---" >> "$BUNDLE/summary.txt"
curl -s -D - -o /dev/null -H "Authorization: Bearer $TOKEN" \
  "https://api.canva.com/rest/v1/designs?limit=1" 2>&1 \
  | grep -iE "(x-ratelimit|retry-after|content-type|date)" \
  >> "$BUNDLE/summary.txt" 2>/dev/null || echo "No rate limit headers" >> "$BUNDLE/summary.txt"

# 4. DNS resolution
echo "" >> "$BUNDLE/summary.txt"
echo "--- DNS Resolution ---" >> "$BUNDLE/summary.txt"
nslookup api.canva.com >> "$BUNDLE/summary.txt" 2>&1 || echo "nslookup not available" >> "$BUNDLE/summary.txt"

# 5. TLS check
echo "" >> "$BUNDLE/summary.txt"
echo "--- TLS Handshake ---" >> "$BUNDLE/summary.txt"
curl -sv "https://api.canva.com/rest/v1/users/me" 2>&1 \
  | grep -E "(SSL|TLS|Connected)" >> "$BUNDLE/summary.txt" 2>/dev/null || true

# 6. Environment info
echo "" >> "$BUNDLE/summary.txt"
echo "--- Environment ---" >> "$BUNDLE/summary.txt"
echo "Node: $(node --version 2>/dev/null || echo 'not found')" >> "$BUNDLE/summary.txt"
echo "OS: $(uname -s -r)" >> "$BUNDLE/summary.txt"
echo "CANVA_CLIENT_ID: ${CANVA_CLIENT_ID:+[SET]}" >> "$BUNDLE/summary.txt"
echo "CANVA_ACCESS_TOKEN: ${CANVA_ACCESS_TOKEN:+[SET]}" >> "$BUNDLE/summary.txt"

# 7. Package bundle
tar -czf "$BUNDLE.tar.gz" "$BUNDLE"
echo ""
echo "Bundle created: $BUNDLE.tar.gz"
```

### Step 2: Programmatic Diagnostic

```typescript
// src/canva/diagnostics.ts
interface DiagnosticResult {
  check: string;
  status: 'pass' | 'fail' | 'warn';
  details: string;
  durationMs: number;
}

async function runCanvaDiagnostics(token: string): Promise<DiagnosticResult[]> {
  const results: DiagnosticResult[] = [];

// Check 1: API reachability
  const start1 = Date.now();
  try {
    const res = await fetch('https://api.canva.com/rest/v1/users/me', {
      headers: { 'Authorization': `Bearer ${token}` },
    });
    results.push({
      check: 'API Reachability',
      status: res.ok ? 'pass' : res.status === 401 ? 'fail' : 'warn',
      details: `HTTP ${res.status}`,
      durationMs: Date.now() - start1,
    });
  } catch (e: any) {
    results.push({ check: 'API Reachability', status: 'fail', details: e.message, durationMs: Date.now() - start1 });
  }

// Check 2: Token validity
  const start2 = Date.now();
  try {
    const res = await fetch('https://api.canva.com/rest/v1/users/me', {
      headers: { 'Authorization': `Bearer ${token}` },
    });
    if (res.ok) {
      const data = await res.json();
      results.push({
        check: 'Token Validity',
        status: 'pass',
        details: `user_id: ${data.team_user.user_id}`,
        durationMs: Date.now() - start2,
      });
    } else {
      results.push({ check: 'Token Validity', status: 'fail', details: `HTTP ${res.status}`, durationMs: Date.now() - start2 });
    }
  } catch (e: any) {
    results.push({ check: 'Token Validity', status: 'fail', details: e.message, durationMs: Date.now() - start2 });
  }

// Check 3: Design list (tests design:meta:read scope)
  const start3 = Date.now();
  try {
    const res = await fetch('https://api.canva.com/rest/v1/designs?limit=1', {
      headers: { 'Authorization': `Bearer ${token}` },
    });
    results.push({
      check: 'Scope: design:meta:read',
      status: res.ok ? 'pass' : res.status === 403 ? 'warn' : 'fail',
      details: res.ok ? 'Scope active' : `HTTP ${res.status} — scope may not be enabled`,
      durationMs: Date.now() - start3,
    });
  } catch (e: any) {
    results.push({ check: 'Scope: design:meta:read', status: 'fail', details: e.message, durationMs: Date.now() - start3 });
  }

return results;
}

// Print report
const results = await runCanvaDiagnostics(process.env.CANVA_ACCESS_TOKEN!);
for (const r of results) {
  const icon = r.status === 'pass' ? 'OK' : r.status === 'warn' ? 'WARN' : 'FAIL';
  console.log(`[${icon}] ${r.check}: ${r.details} (${r.durationMs}ms)`);
}
```

## Sensitive Data Handling

**ALWAYS REDACT before sharing:**
- Access tokens and refresh tokens
- Client secrets
- User IDs (if privacy-sensitive)

**Safe to include:**
- HTTP status codes and error messages
- Response headers (rate limit info)
- Latency measurements
- SDK/runtime versions

## Error Handling

| Item | Purpose | Included |
|------|---------|----------|
| HTTP status from `/v1/users/me` | Auth validation | Yes |
| Rate limit headers | Throttling diagnosis | Yes |
| DNS resolution | Network path | Yes |
| TLS handshake | Certificate issues | Yes |
| Environment versions | Compatibility | Yes |
