Recharts 2.1.14: Typing error at DefaultTooltipContent.tsx:83. value and name could be undefined while it is not expected.

• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

https://github.com/recharts/recharts

Steps to reproduce

• Install Recharts lib in a typescript project.
• Use Tooltip from Recharts.
• See the typing error.
• Open src/component/DefaultTooltipContent.tsx in an IDE
• See the typing error at DefaultTooltipContent.tsx:83 for value & name variables

What is expected?

The variables Value and Name should never be undefined at this state, but typescript seems to think it can still happen and create an error.

What is actually happening?

For the value variable
Argument of type 'TValue | undefined' is not assignable to parameter of type 'TValue'.
'TValue' could be instantiated with an arbitrary type which could be unrelated to 'TValue | undefined'.ts(2345)

For the name variable
Argument of type 'TName | undefined' is not assignable to parameter of type 'TName'.
'TName' could be instantiated with an arbitrary type which could be unrelated to 'TName | undefined'.

Environment	Info
Recharts	v2.1.14
React	18.2.0

Is it already fixed ? I faced the same issue but after installing recharts@latest the error was gone.

This part of the issue seems resolved though #3008 is still open. @gabgagnon Can you confirm that the latest allows you to use a tooltip without this specific error? I can't reproduce even with 2.1.14. Will close this once confirmed

This is fixed, closing
