This is ok bu when i do like this
Type '"test"' is not assignable to type '"eq" | "ne" | "lt" | "gt" | "lte" | "gte" | "in" | "nin" | "contains" | "ncontains" | "containss" | "ncontainss" | "between" | "nbetween" | "null" | "nnull" | "startswith" | "nstartswith" | ... 7 more ... | "and"'.ts(2322)
IDataContext.d.ts(23, 5): The expected type comes from property 'operator' which is declared here on type 'CrudFilter'

When using hooks like useList
, make sure to use the extended type for the operators. Here’s an example:
4. Ensure Type Compatibility:
If you encounter type errors, make sure that the extended type is used consistently throughout your code. You might need to update type definitions in your data provider or other parts of your application to accept the extended operators.
