Quick reference for the most common Figma REST API and Plugin API errors, with exact error messages and working solutions.
| 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 |
# Test your token
curl -s -o /dev/null -w "%{http_code}" \
-H "X-Figma-Token: ${FIGMA_PAT}" \
https://api.figma.com/v1/me
# 200 = token valid, 403 = invalid/expired
# Check what scopes your request needs
# file_content:read -> GET /v1/files/:key
# file_comments:read -> GET /v1/files/:key/comments
# file_variables:read -> GET /v1/files/:key/variables/local
# webhooks:write -> POST /v2/webhooks
Common 403 causes:
file_content:read but calling comments endpoint)// Figma returns these headers on 429:
// Retry-After: <seconds> -- wait this long before retrying
// X-Figma-Rate-Limit-Type: <type> -- "low" or "high" tier
// X-Figma-Plan-Tier: <plan> -- your plan level
async function handleRateLimit(response: Response) {
if (response.status === 429) {
const retryAfter = parseInt(response.headers.get('Retry-After') || '60');
const limitType = response.headers.get('X-Figma-Rate-Limit-Type');
console.warn(`Rate limited (${limitType}). Retrying in ${retryAfter}s`);
await new Promise(r => setTimeout(r, retryAfter * 1000));
return true; // signal to retry
}
return false;
}
# 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"'
null// 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}`);

| 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 |

When the diagnostic itself fails, work outside-in before re-consulting the catalog:
| Symptom | Cause | Solution |
|---|---|---|
Every call returns 401, even /v1/me | Token revoked, expired, or wrong header (Authorization vs X-Figma-Token) | Regenerate the PAT; PATs use X-Figma-Token, OAuth uses Authorization: Bearer |
| Diagnostic script (Step 4) hangs | No timeout on the probe requests | Add --max-time 15 to curl / AbortSignal.timeout() in fetch |
| Error not in the catalog | New API behavior or plugin-API error mistaken for REST | Check Step 3 (plugin errors) and status.figma.com before filing |
| Fix applied but error persists | Cached 4xx response or stale token in another env | Bust caches; verify which env's token the failing process actually loaded |
