Is it possible to restrict the req.query in NextJS NextApiRequest to only accept string types instead of string | string[]? For instance, if someQueryParam is currently of type string | string[], but I need it to be just a string.
export default async function handler(
req: NextApiRequest,
res: NextApiResponse<Response>
) {
const { someQueryParam } = req.query;
// Passing someQueryParam as a string into a function call
const result = functionCall(someQueryParam)
}
When attempting to pass someQueryParam into a function that only accepts string, TypeScript throws an error:
Argument of type 'string | string[]' is not assignable to parameter of type 'string'.
Type 'string[]' is not assignable to type 'string'.
Here is the definition of NextApiRequest in the Next.js library for reference:

I am also open to suggestions on how to utilize someQueryParam as a string type within the handler before passing it into the function.
