TL;DR

Append a unique identifier or number to the node name when copying and pasting to avoid naming conflicts.

Guidance

  • Identify the node naming convention and modify it to include a unique identifier when copying nodes.
  • Consider implementing an auto-incrementing naming scheme to simplify the process.
  • Verify that the pasted node has a unique name by checking the node's properties after pasting.
  • If the issue persists, review the n8n version and consider upgrading to a newer version if available, as this might be a known issue that has been resolved in later versions.

Notes

The provided information does not specify how the node naming is handled internally by n8n, so the suggested solution focuses on modifying the node name when copying and pasting.

Recommendation

Apply workaround: Append a unique identifier or number to the node name when copying and pasting, as this provides an immediate solution to the naming conflict issue.
