Why Does the Code Node Timeout in My n8n Cloud Workflows?
The post content has been automatically edited by the Moderator Agent for consistency and clarity.
Want to use over 200+ MCP servers inside your coding tools like Cursor?
I'm experiencing an issue on the n8n Cloud plan where all nodes run smoothly and the workflow completes in under one second, except when I add a Code Node (JavaScript). The workflow times out at the Code Node regardless of the code's complexity or the data volume.
Notably, replacing the Code Node with a Set Node that uses an equivalent inline expression works perfectly, even with the same data. This sporadic timeout issue seems like it could be related to server-side resource or compatibility limitations.
Here are the specifics about my environment:
- n8n version: 1.72.1
- Database (default: SQLite): n8n cloud
- Running n8n via: n8n cloud
- Operating system: n8n cloud
Has anyone encountered a similar issue or found a solution? Any insights into resolving this problem would be appreciated.

Below is some guidance based on known limitations and best practices with the Code node on n8n Cloud:
What’s Likely Happening
On n8n Cloud, the Code node runs in an isolated, sandboxed environment with some limitations compared to a self-hosted instance. Because of these additional restrictions and startup overhead, even simple JavaScript code may take longer to execute—enough to hit timeout limits. In contrast, using inline expressions in a Set node bypasses this overhead, which is why you see faster execution there.
Recommendations & Solutions
-
Use Alternative Nodes:
If your data transformation can be accomplished with inline expressions (via the Set node or Expression Editor), that is the recommended approach on n8n Cloud to avoid the performance issues associated with the Code node. -
Consider the Execution Mode:
The Code node has two modes: Run Once for All Items and Run Once for Each Item. Depending on your use case, switching the mode might reduce the overhead. However, if you still experience timeout issues, it’s best to replace it with a Set node where applicable. -
Self-Hosted Option:
If your workflow critically depends on the Code node for more advanced logic and performance becomes an issue, you might consider self-hosting n8n. Self-hosted instances provide more flexibility (including support for external npm modules) and often have fewer resource limitations.
Next Steps
-
Review Your Workflow Needs:
Evaluate if the transformation logic in the Code node could be implemented with expressions or other dedicated nodes (like the Set node). -
Contact Support:
Since this appears to be a resource or compatibility limitation on n8n Cloud, reaching out to n8n support might help verify this behavior and advise if there’s a known workaround or upcoming update. -
Monitor Execution Modes:
Double-check that your Code node is configured in the most efficient mode for your use case.
Hopefully, these insights help clarify why you’re encountering timeouts with the Code node on n8n Cloud and provide you with possible workarounds.
