Returning data using fetch

[yosiasz]

Greetings!

I am returning data as follows

handlebars.registerHelper("getEntities", () =>
  fetch('http://localhost:5000/api/v4/entities?search=7676')
    .then(response => response.json())
    .then(data => {
      return data
    })
);

Data returned is

{
    "event": "DevicesM",
    "podName": "alliswell",
    "Time": "2023-06-09T07:56:19.483Z",
    "totalConnected": "30",
    "totalPType": "8",
    "totalJType": "2",
    "totalBType": "7",
    "totalWType": "2",
    "totalFIType": "11"
}

1. Is the return ok or do I need to use something like a spread? return [...new Set(context.map(data => data[key]))];
2. on the Content side of things I am not getting any data with the following

<div>
  {{#each (getEntities data)}}
    {{ event }}; 
  {{/each}}
</div>

Been at this for 3 hours and I give up Thanks!

it's async call and I handlebars can't wait for async call to display it

I will keep it opened for now to explore a way to add async Handlebars handlers.

does not seem anywhere near the horizon

We implemented the JavaScript Values editor in the latest version of the Static Data Source, which should be used instead of implementing asynchronous calls in the panels.
