The error specifically triggers on {children} on this line.
return <Fragment>{children}</Fragment>

Hi! Thanks to report this bug! Do you encounter the bug when you disable the formatter? or the linter?

The issue is probably the code action applied to this snippet:

function name(params) {
  return <Fragment>{children}</Fragment>
}
