Why can't I set a variable using c.set?

[davididos]

I am getting a typescript error for the following code:

Here is the full typescript error:

No overload matches this call.
Overload 1 of 2, '(key: "jwtPayload", value: any): void', gave the following error.
Argument of type '"userId"' is not assignable to parameter of type '"jwtPayload"'.
Overload 2 of 2, '(key: "userId", value: string): void', gave the following error.
Argument of type 'unknown' is not assignable to parameter of type 'string'.

28 c.set("userId", payload.id);
~~~

If I change the key of the set method to "jwtPayload" it works. But this doesn't make any sense to me. It would seem to imply that you can only set one variable named "jwtPayload", which conflicts with the examples given in the documentation.

Sorry if I have misunderstood something obvious, I am new to both Hono and typescript.

Thanks
