Water Summary Data returns as "Undefined"

[iPh33r]

Am I "getting" the data correctly? I just want to display the total water I've logged so far that day. I print the results to the console and I get "{ summary: {} }" in companion and "undefined" in app.

companion/index.js

fetch(`https://api.fitbit.com/1/user/-/foods/log/water/date/${todayDate}.json`, {
    method: "GET",
    headers: {"Authorization": `Bearer ${accessToken}`}
  })
  .then(function(res) {return res.json();})
  .then(function(data) {
    let myData = {summary: {water:data.summary}};
    console.log(myData);
    if (messaging.peerSocket.readyState === messaging.peerSocket.OPEN) {
      messaging.peerSocket.send(myData);
    }
  })

app/index.js

// Message is received from companion
messaging.peerSocket.onmessage = evt => {
    console.log(evt.data.water);
    myWater.text = evt.data.water;
};

After trying different combinations of words, I accidentally stumbled upon the right format. The Web API formatting was no help explaining the reason behind the syntax.

The proper way to call the data would be: 

let myData = {"water":data.summary.water};

Then to display that data:

myWater.text = evt.data.water; //the last word is what you wrote in the quotation marks in Companion.

(I wrote "blah" in the quotation marks and called "evt.data.blah" and it worked just fine.)
