extent analysis

TL;DR

Check the n8n version and consider upgrading to a newer version if available, as the current version 2.17.5 may have known issues or limitations.

Guidance

  • Review the n8n documentation for any known issues or deprecations in version 2.17.5 that may be related to the problem.
  • Verify that the postgres database connection is stable and properly configured.
  • Check the nodeJsVersion and ensure it is compatible with the n8n version being used.
  • Consider increasing the logging level or enabling debug mode to gather more information about the issue.

Notes

The provided information lacks specific details about the error or problem being experienced, making it challenging to provide a precise solution. Further investigation and logging may be necessary to identify the root cause.

Recommendation

Apply workaround: Given the lack of information, it's recommended to start by gathering more logs and details about the issue before considering an upgrade or making significant changes.
