V7: Controller ```value``` type and ```watch``` type is ```never``` when using ```watch``` inside a Field array

Describe the bug As Shown in the sandbox, I was trying to access a value using the watch method from inside the field components. but the return type is always never. The Same type occurs in the Controller at the same component when trying to access the value. Also setting a value with setValue() is not possible due to the never type.

Am I doing something wrong ?

Expected behavior watch method should return the proper type defined the the type definitions, instead returns never.

Screenshots If applicable, add screenshots to help explain your problem.

screenshot from the actual project, somehow the type here is never while in the sandbox the type is any.

Thanks, @ymor I think the next release of TS will improve on that (https://github.com/microsoft/TypeScript/pull/43361).

@Gencko94 You need to use something like the following for TS to get the correct type. `variationValues.${index}.priceEnabled` as `variationValues.0.priceEnabled`

I assume this is some form of typescript limitation.
