Error "Expression SectorID eq null is not supported"



On my PowerApps application, I have a dropdown that has its allowed values based on the selected value of another dropdown, using the filter function below: 


Filter([@MasterData_Subcategory]; SectorID = DataCardValue14.Selected.CategoryID)





However, the following error shows when I run the app: "Expression SectorID eq null is not supported"


I don't understand why this error is showing up since there are no null values in any of the tables (I've attached both in this post) and every value has a match, ensuring that there are no comparisons that would return null values. Could you help me with this? Thanks!
