# Figma Common Errors

## Overview
Quick reference for the most common Figma REST API and Plugin API errors, with exact error messages and working solutions.

## Prerequisites
- Figma API credentials configured
- Access to your application logs or browser console

## Instructions

### Step 1: Identify the Error Category

#### REST API HTTP Errors

| Status | Error | Cause | Solution |
|--------|-------|-------|----------|
| 400 | Bad Request | Malformed request, invalid node IDs | Verify node ID format (`pageId:nodeId`, e.g., `0:1`) |
| 403 | Forbidden | Invalid token, wrong scopes, no file access | Regenerate PAT with correct scopes; verify file sharing |
| 404 | Not Found | Wrong file key, deleted file, wrong endpoint | Check file key from URL; verify file exists |
| 429 | Rate Limited | Too many requests | Read `Retry-After` header; implement backoff |
| 500 | Internal Server Error | Figma server issue | Retry with exponential backoff; check status.figma.com |

### Step 2: Diagnose Specific Errors

#### 403 Forbidden -- Token Issues
```bash
# Test your token
curl -s -o /dev/null -w "%{http_code}" \
  -H "X-Figma-Token: ${FIGMA_PAT}" \
  https://api.figma.com/v1/me
# 200 = token valid, 403 = invalid/expired

# Check what scopes your request needs
# file_content:read  -> GET /v1/files/:key
# file_comments:read -> GET /v1/files/:key/comments
# file_variables:read -> GET /v1/files/:key/variables/local
# webhooks:write     -> POST /v2/webhooks
```

Common 403 causes:
- PAT expired (90-day maximum lifetime)
- Token missing required scope (e.g., using `file_content:read` but calling comments endpoint)
- File not shared with the token owner
- OAuth token not refreshed after expiry

#### 429 Rate Limited
```typescript
// Figma returns these headers on 429:
// Retry-After: <seconds>            -- wait this long before retrying
// X-Figma-Rate-Limit-Type: <type>   -- "low" or "high" tier
// X-Figma-Plan-Tier: <plan>         -- your plan level

async function handleRateLimit(response: Response) {
  if (response.status === 429) {
    const retryAfter = parseInt(response.headers.get('Retry-After') || '60');
    const limitType = response.headers.get('X-Figma-Rate-Limit-Type');
    console.warn(`Rate limited (${limitType}). Retrying in ${retryAfter}s`);
    await new Promise(r => setTimeout(r, retryAfter * 1000));
    return true; // signal to retry
  }
  return false;
}
```

#### 404 Not Found
```bash
# Verify your file key is correct
# URL format: https://www.figma.com/design/<FILE_KEY>/<file-name>
# The file key is the string between /design/ and the next /

# Test the file key
curl -s -H "X-Figma-Token: ${FIGMA_PAT}" \
  "https://api.figma.com/v1/files/${FIGMA_FILE_KEY}" \
  | jq '.name // "FILE NOT FOUND"'
```

#### Images Endpoint Returns `null`
```typescript
// GET /v1/images/:key returns null for nodes that cannot render
const images = await exportImages(['0:1', '0:2']);

for (const [nodeId, url] of Object.entries(images)) {
  if (url === null) {
    // Node failed to render. Common causes:
    // - Node is invisible (visibility: false)
    // - Node has 0% opacity
    // - Node ID does not exist in the file
    // - Node has no visual content (e.g., an empty frame)
    console.error(`Failed to render node ${nodeId}`);
  }
}
```

### Step 3: Plugin API Errors

| Error | Context | Cause | Solution |
|-------|---------|-------|----------|
| `figma is not defined` | Node.js / browser | Running plugin code outside Figma sandbox | Plugin code only runs inside Figma desktop app |
| `Cannot read property of undefined` | Plugin | Accessing deleted node reference | Re-query node: `figma.getNodeById(id)` |
| `Plugin timed out` | Plugin | Operation took too long | Use `figma.commitUndo()` and batch operations |
| `Quota exceeded` | Plugin | Too many nodes created | Limit to ~5000 nodes per operation |
| `Permission denied` | Plugin | Missing `manifest.json` permission | Add required permission to `permissions` array |

### Step 4: Quick Diagnostic Script
```bash
#!/bin/bash
echo "=== Figma API Diagnostics ==="

# 1. Check Figma service status
echo -n "Figma Status: "
curl -s -o /dev/null -w "%{http_code}" https://www.figma.com && echo " OK" || echo " DOWN"

# 2. Validate token
echo -n "Token Valid: "
curl -s -o /dev/null -w "%{http_code}" \
  -H "X-Figma-Token: ${FIGMA_PAT}" \
  https://api.figma.com/v1/me

# 3. Check file access
echo -n "File Access: "
curl -s -H "X-Figma-Token: ${FIGMA_PAT}" \
  "https://api.figma.com/v1/files/${FIGMA_FILE_KEY}" \
  | jq -r '.name // "FAILED"'

# 4. Check env vars
echo "FIGMA_PAT: ${FIGMA_PAT:+SET (${#FIGMA_PAT} chars)}"
echo "FIGMA_FILE_KEY: ${FIGMA_FILE_KEY:-NOT SET}"
```

## Output
- Identified error cause from status code and headers
- Applied targeted fix
- Verified resolution with diagnostic commands

## Examples

### Error Wrapper with Actionable Messages
```typescript
function diagnoseFigmaError(status: number, body: string): string {
  switch (status) {
    case 403: return 'Auth failed. Check: (1) PAT not expired (2) correct scopes (3) file shared with you';
    case 404: return 'Not found. Check: (1) file key from URL (2) file not deleted (3) node IDs valid';
    case 429: return 'Rate limited. Implement exponential backoff with Retry-After header';
    case 500: return 'Figma server error. Check status.figma.com and retry with backoff';
    default: return `Unexpected ${status}: ${body}`;
  }
}
```
