extent analysis

TL;DR

Check the workflow configuration and node connections to ensure they are properly set up and not causing the "Connection lost" error.

Guidance

Example

No code snippet is provided as the issue seems to be related to workflow configuration rather than code.

Notes

The issue may be specific to the shared workflow or the n8n environment, and further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Check and adjust the workflow configuration and node connections to resolve the "Connection lost" error, as the issue seems to be related to the workflow setup rather than a version-specific problem.
