What happened

This is difficult to reproduce, as I thought it had to do with copying and pasting two nodes but may be through some other set of circumstances. Regardless, a node ended up with duplicate inputs where only one (i.e. not a collection) is allowed. The console error was a per-invocation one:

[2024-10-07 13:59:58,425]::[InvokeAI]::ERROR --> Non-fatal error in session processor InvalidEdgeError: Edge to node f0bd2ad2-42a9-4382-8ae4-678f683b024f field seed already exists

What you expected to happen

When a node can only accept a single input, I would expect the UI to enforce that behavior.
