FAQ

Questions about List Lambda Functions.

What does the List Lambda Functions action do in AWS Lambda?

Returns all Lambda functions in the connected AWS account + region with name, runtime, and ARN. Useful for inventorying available functions when setting up an Invoke action.

What inputs does List Lambda Functions require?

List Lambda Functions has no required inputs. Sensible defaults are applied if you leave fields blank.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if AWS Lambda returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does List Lambda Functions support batch operations?

Yes. Run List Lambda Functions inside a Loop node to process arrays. Tiny Command handles AWS Lambda's rate limits automatically so you don't have to throttle manually.
