i was devide the data and state of the application into slice,i used the sliceReducer in this project because it have so many component and have a lot of products categories to buy so when i try to make the first components which is about mechanics product this error always display “Ă—
Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
- You might have mismatching versions of React and the renderer (such as React DOM)
- You might be breaking the Rules of Hooks
- You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.”
