TypeScript Type Error When Using rc-select with CSS Modules and Vite.

[junhaoliao]

When using rc-select with CSS Modules and Vite, the following error occurs with exactOptionalPropertyTypes: true enabled:

CSS Module:

/* myStyles.module.css */
.selectBox {
  /* styles */
}

Component:

import styles from "myStyles.module.css"

const MyComponent = () => (
  <Select className={styles["selectBox"]} />
);

Error:

TS2375: Type { className: string | undefined; } is not assignable to type SelectProps<any, DefaultOptionType> with 'exactOptionalPropertyTypes: true'. Consider adding undefined to the types of the target's properties.
Types of property className are incompatible.
Type string | undefined is not assignable to type string
Type undefined is not assignable to type string
