Fix n8n Execution Glitch

I’m running several automated processes in n8n and have hit a wall: the workflows throw errors with unexpected behavior that only shows up while they are running. Design-time edits, node configuration, and saving all look fine—problems surface exclusively at execution.

Here’s what I need from you:
• Pin-point why the workflow misbehaves during execution.
• Deliver a clean, reproducible fix or robust workaround.
• Provide a brief summary of what went wrong and how you corrected it so I can avoid the same pitfall in future builds.

Access to my n8n instance and any pertinent logs can be arranged as soon as we agree on a start time. If you rely on Node.js debugging, TypeScript, Postgres, or REST-API tracing, mention it so we can align on tooling before you dive in.

Acceptance criteria:
• Workflows run to completion without unexpected branches, missing data, or silent failures.
• No new regressions introduced.
• Clear explanation of the root cause and the edits performed, delivered in a short markdown file.

Looking forward to getting these automations running smoothly again.
