Validation error: Validation failed: data should NOT have additional properties

I just get the err

Validation error: Validation failed: data should NOT have additional properties

With a workflow from node serialport. I can't debug it though because I don't know what's causing the issue. I tried bisecting it a bit with no luck.

Looks like it might be the concurrency options. If I remove them, it stops erroring but doesn't render anything.
