Dear Developers, I hope this message finds you well. I am writing to request your assistance in resolving a technical issue I am facing. I am trying to make a request from a public endpoint within my app to a private endpoint within the same app. I am using Axios for this purpose and my code appears to be written correctly:

app.post("/api/customer", async (req, res) => {
    const customerInput = req.body;

    try {
      const createCustomerResponse = await graphqlClient.query({
        data: { query: CREATE_CUSTOMER, variables: { input: customerInput } },
      });
      const data = createCustomerResponse.body.data.customerCreate;
      const { userErrors, customer } = data;
      if (userErrors.length > 0) {
        throw new GraphqlError(userErrors);
      }

      const customerId = customer.id.match(/\d*$/)[0];
      const response = await axios.post("https://1234.ngrok.io/api/send-invite", customerId);
      const result = await response.json();
      console.log(result);

      res.status(200).json({ customer });
    } catch (error) {
      if (error instanceof GraphqlError) {
        res.status(422).json({
          message: "GraphQL User Errors",
          errors: error.errors,
        });
      } else if (error instanceof Error) {
        res.status(400).json({
          message: "Wrong Data Format",
          error: error,
        });
      } else {
        res.status(500).send(error);
      }
    }
  });

  app.post("/api/send-invite", async (req, res) => {
    try {
      const id = req.body;

      const customerInviteResponse = await restClient.post({
        path: "/customers/" + id + "/send_invite",
      });
      const customerInvite = customerInviteResponse.body.customer_invite;

      res.status(200).json(customerInvite);
    } catch (error) {
      res.status(500).send(error);
    }
  });

However, I am encountering an error message and I am seeking your help in resolving it:

Could you please provide some guidance on how I can resolve this issue? Thank you in advance for your assistance.
