Difficulties Creating Space Time Cube

[KLMapes]

I am currently working in ArcGIS Pro 2.7.2 with the Create Space Time Cube by Aggregating Points tool. I have a point layer of fire occurrences that I am trying to aggregate to county polygons. I keep running into an issue when trying to define my Defined Polygon Locations input where the tool is not allowing me to select a Location ID field. It is giving me an error 000308 for Invalid Field Type. I cannot find any documentation on what field types are supported so I can correct this error. I have attached a screen shot of the tool inputs.
