Issue in 2019.3 with Python tool as first tool in workflow

Question

I'm using snakeplane to develop a custom tool and it was working fine until I took the optional input connection away and made it the first tool to execute in the workflow.

Here's a screenshot showing the debug without the input to the custom tool and then adding the input (with 0 records) back to the custom tool.

Thanks @DrewE ! I got some time today to make a quick example tool to show the behavior. Posted to github as requested.

This is definitely undesired, if you post an issue on the Github repo we'd be happy to address this in the near future!

Hey @BlytheE

Sorry, been busy and unable to create a tool that I can share here. A confirmation that this is expected/unexpected behavior might be enough for now, until I can get something back to you.
