Error when use "[key: `data-${string}`]: string;"

[melodyJie]

Case:

export interface ComponentProps {
  /**
   * @TJS-ignore
   */
  [key: `data-${string}`]: string;
}

Error:

Error: error: Error: Not supported: IndexSignatureDeclaration with index symbol other than a number or a string

What worked for me is changing from

interface Config {
  [key: `data-${string}`]: string;
}

to

type Config = Record<`data-${string}`, string>
