Recurring 'Maximum Call Stack Size Exceeded' Error in n8n v1.65+ with Postgres on Docker
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?
The “Maximum call stack size exceeded” error was fixed in n8n version 1.61.0:
- n8n@1.61.0 Release · n8n-io/n8n · GitHub
- Fix for MySQL Node – Maximum call stack error with a large number of rows · n8n-io/n8n · GitHub
However, the bug has reoccurred in versions 1.65 and above. I am currently running n8n version 1.74.3 on Docker, using Postgres as the database on AWS Linux AMI. It appears that while the previous fix was tailored for MySQL, a similar issue might be affecting Postgres implementations in later versions.
Could you please investigate and address this recurring issue?

Thanks for the detailed report. The “Maximum call stack size exceeded” error was indeed addressed in v1.61.0, and it appears that with changes in later versions (v1.65+ and now v1.74.3) the issue may be recurring in your environment. Since you’re running Postgres on Docker (on AWS Linux AMI), this isn’t directly related to the MySQL node fix but might stem from similar recursive processing in parts of the codebase that handle large datasets.
At this point, the best approach is to file (or update) an issue on our GitHub repository with as many reproduction details as possible, including:
- The steps or workflow that lead to the error
- Any relevant logs or error stack traces
- Your configuration details (which you’ve already provided)
This information will help our development team pinpoint whether additional adjustments are needed in the affected code paths. I’ll make sure your feedback is passed along, and in the meantime, keep an eye on the release notes for any updates or fixes regarding this issue.
If you need guidance on filing a detailed bug report, please refer to our documentation on GitHub issue reporting.
Thank you for your patience and for helping us improve n8n!
