Issue with Inferred Return Type in Effect Function

const validateRequestSignature = (
  requestBody: string,
  signatureHeader: string | null
) => {
  if (!signatureHeader) {
    return Effect.fail({
      message: 'Missing webhook signature header',
    } as const);
  }
  const signature = 'secret' + requestBody;
  const hashedSignature = crypto
    .createHash('sha256')
    .update(signature)
    .digest('hex');
  return hashedSignature === signatureHeader
    ? Effect.succeedNone()
    : Effect.fail({ message: 'Invalid webhook signature' } as const);
};

Effect.Effect<never, {
  readonly message: "Missing webhook signature header";
