[BUG] Custom Connnector With Only Optional Inputs Does Not Render Input Fields

problem.png

My connector has a single optional input (modelQuery), but when I load the connector it skips the input and goes straight to loading data.

However if there is a mandatory parameter before the optional one, then both get rendered just fine. problem.png

The expected behaviour is that if the only parameter is an optional one, then that parameter should still get rendered/shown to the user.

I have already done this, it still skips rendering the optional input. @v-frfei-msft
