Sorry for the inconvenience. You can either cast to any or stick with the older version of TypeScript.

This issue doesn't apply to the newer React template (because it doesn't use TypeScript) so it's effectively fixed, in that no change to the code in our repos would be relevant, hence closing.

I have the same issue and cannot solve some errors (e.g. TS2322, TS2344) by just casting to any. In the first place there seems still typescript in the latest reactredux template. How can I get a template without typescript?

[Vladis466]

@SteveSandersonMS Could you provide some clarification on why the newer version of the template does not use typescript and when/where we could get it?

Thank you!
