Property X does not exist on type

[paul-uz]

I am parsing an object of query params and when accessing the various values, I'm getting the following error

"Property 'size' does not exist on type 'string | ParsedQs | string[] | ParsedQs[]'. Property 'size' does not exist on type 'string'.ts(2339)"

Code

event: {
    queryStringParameters: { 'page[size]': '2' }
}

const queryParams = qs.parse(event.queryStringParameters);
const pageSize = queryParams.page?.size; // error on this line

Oddly, the code works fine, just I get these error messages that are distracting me.

This package does not contain types, so you'd need to file this on DefinitelyTyped.

@ljharb erm OK.

Alternatively, how can I stop those errors appearing at all?

Stop using typescript?

I’m sure you could cast the return value to a different type and avoid the type error.

I'm not using typescript. But I still see the errors in VSCode.

Ah, I'm not sure how to turn them off entirely, there's probably a vscode setting for it.

Otherwise, the types would have to be fixed in DefinitelyTyped.
