Typescript error: This expression is not callable. Type ‘never’ has no call signatures

I am getting a TypeScript error on onToggle(eventKey === activeEventKey ? null : eventKey) – This expression is not callable. Type ‘never’ has no call signatures. I am not sure how to resolve this.

import React from 'react'
import useAccordionContext from '../../../hooks/useAccordionContext'

interface Props {
  eventKey: string | undefined
  id: string | undefined
  className: string
  onClick: (event: React.MouseEvent<HTMLButtonElement, MouseEvent>) => void
}

const useAccordionClick = (
  eventKey: string | undefined,
  onClick: {
    (event: React.MouseEvent<HTMLButtonElement, MouseEvent>): void
    (arg0: React.MouseEvent<HTMLButtonElement, MouseEvent>): void
  }
) => {
  const { onToggle, activeEventKey } = useAccordionContext()
  return (event: React.MouseEvent<HTMLButtonElement, MouseEvent>) => {
    onToggle(eventKey === activeEventKey ? null : eventKey)

    if (onClick) {
      onClick(event)
    }
  }
}

const Toggle: React.FC<Props> = ({
  eventKey,
  onClick,
  children,
  ...otherProps
}) => {
  const accordionClick = useAccordionClick(eventKey, onClick)
  return (
    <button
      onClick={accordionClick}
      {...otherProps}
    >
      {children}
    </button>
  )
}

export default Toggle
