Shape from Pen Tool Not Allowing Type Inside Area
I've created a closed shape using the pen tool and would like to fill it with text but I keep getting the error "You must click on a non-compound, non-masking path to create text inside a path".
It is not a compound path. It is not a clipping mask. I cannot convert it to a shape.
I have tried isolating, joining, and making & releasing a compound path. I've tried clicking inside the shape, on the border of the shape, directly on the anchor points. Clearly none of this worked.

How do I get the text inside the non-compound, non-masking shape I've created with the pen tool? I've searched Adobe and Stack Exchange for hours and can find no questions that replicate my situation. I've run into this situation a number of times. I'm sure there's a solution somewhere.
