n8n errors / Other

n8n may have run out of memory while running this execution

platform: n8n / category: Other

Cause

The Node.js process exhausts heap memory, often from processing large binary files or accumulating many large items across nodes.

Fix

Filter or project only needed fields early. Process binary data in chunks/streams rather than whole. Split monolithic workflows into sub-workflows to bound per-execution memory. Self-hosted: raise the heap with NODE_OPTIONS=--max-old-space-size=4096; on Cloud, upgrade to a higher-memory plan.

Hitting an automation error we have not covered?

AutomateLab builds and debugs n8n, Make, and agent workflows as fixed-scope projects. If something is broken in production, tell us what you are seeing.
