Contingent Error 999999

[GIS_Solutions]

Hi everyone,

When I define a contingent value, I get such an error, does anyone have any comments about the reason?
Are there any data type constraints or requirements for the contingent value?

I'm using ArcGIS Pro 2.8.3, File Geodatabase

I would do what the error says and contact ESRI technical support.  Or you could do a search to find a possible bug here: https://support.esri.com/en/Search-Results#search?q=arcgis-pro&content-type=Bugs
