Use this page when a workflow fails validation, does not trigger, pauses unexpectedly, cannot call a provider, or delivers unexpected results.
| Symptom | Check |
|---|
| Missing required fields | Open each node with a validation error and compare against its action schema |
| Broken expression | Confirm referenced node IDs, trigger fields, props, and loop variables exist |
| Missing connector | Select or create the required connector type |
| Unsupported wallet chain | Confirm the action supports the selected chain and wallet |
| Invalid graph | Check branches, loops, child nodes, and unreachable nodes |
| Trigger type | Check |
|---|
| Manual | Confirm the workflow has a live version or valid draft test input |
| Schedule or cron | Confirm the workflow is active, not paused, and schedule config is valid |
| Webhook | Confirm URL/secret, method, content type, and payload shape |
| EVM log | Confirm chain, address, topics, deployment block, and listener state |
| Slack or SaaS | Confirm connector health, provider permissions, event subscription, and filters |
| Payment or market event | Confirm provider account, event type, and filter criteria |
- Open the run and find the first failed execution.
- Inspect the resolved node input.
- Compare the input to the action schema.
- Check connector or wallet requirements.
- Inspect sanitized provider error details.
- Add a format, branch, or code-transform node if incoming data needs normalization.
The most useful debugging view is usually the node input after expression resolution. It shows what the action actually received.
| Error type | Likely cause |
|---|
| Unauthorized | Token expired, provider account revoked, missing scope |
| Forbidden | Provider account lacks resource access |
| Not found | Channel, shop, sheet, customer, or resource ID is wrong |
| Rate limited | Provider throttling or too many workflow runs |
| Invalid payload | Action schema or provider API expectation changed |
| Error type | Likely cause |
|---|
| Insufficient funds | Missing token balance or native gas token |
| Reverted transaction | Contract condition failed, slippage, allowance, deadline, or chain state changed |
| Bad address | Invalid destination, wrong chain, or malformed token address |
| Nonce conflict | Concurrent wallet activity or stale pending transaction |
| Missing wallet | Permission, setup, or unsupported action configuration |
| Symptom | Check |
|---|
| No delivery | Hook enabled, event type selected, destination URL reachable |
| Signature failure | Correct secret and canonical payload handling |
| Repeated retries | Endpoint non-2xx responses or timeout |
| Duplicate side effects | Missing idempotency in your receiver |
| Missing fields | Receiver assumes optional fields are always present |
Pause a workflow if it repeatedly fails, calls an expensive provider unexpectedly, emits duplicate webhooks, or could perform an unsafe wallet operation. Repair and test a draft before resuming.
