How do you pass body data with an Amplify REST request?

Question

I'm using the AWS amplify REST API to make a get request to my lambda function in React Native. The API/Lambda function was generated by the Amplify CLI.

  const getData = async (loca) => {
    const apiName = "api1232231321";
    const path = "/mendpoint";
    const myInit = {
      body: {
        name: "bob",
      },
      queryStringParameters: {
        location: JSON.stringify(loca),
      },
    };

    return API.get(apiName, path, myInit);
  };

Unless I remove the body from this request, it just returns Error: Network Error with no other details. I seem to be able to get the queryStringParameters just fine though if I remove the body object.

If I do this, the request goes through fine without errors

const myInit = JSON.stringify({
  body: {
    name: "bob",
  },
});

But the body in the event (event.body) in lambda is always null. Same result if change body to data as well. My second thought was that perhaps I can only pass body data with a POST request however the docs seem to show that you can use a GET request since it documents how to access said body data ...

Lambda function

exports.handler = async(event) => {
  const response = {
    statusCode: 200,
    body: JSON.stringify(event),
  };
  return response;
};

How do I correctly pass body data?

The Amplify SDK won't send a body on a API.get() call. You're first example looks fine but you'll need to use API.post() (or put) instead.

  const getData = async (loca) => {
    const apiName = "api1232231321";
    const path = "/mendpoint";
    const myInit = {
      body: {
        name: "bob",
      },
      queryStringParameters: {
        location: JSON.stringify(loca),
      },
    };

    return API.post(apiName, path, myInit);
  };

Below code works for me to send an SMS

var AWS = require('aws-sdk');

exports.handler = function (event, context, callback) {

    console.log("Log-Event:"+event.message);
    console.log("Log-Event:"+event.phoneNUmber);
    // Create publish parameters
var params = {
    Message: event.message, /* required */
    PhoneNumber: event.phoneNumber,
    MessageStructure: 'string'
  };
  var sns = new AWS.SNS();

  // Create promise and SNS service object
var publishTextPromise = sns.publish(params).promise();

// Handle promise's fulfilled/rejected states
publishTextPromise.then(
  function(data) {
    console.log("MessageID is " + data.MessageId);
  }).catch(
    function(err) {
    console.error(err, err.stack);
  });
};
