Problem calling functions on Report object

powerbi_noob — Sat, 24 Jun 2017 23:04:01 GMT

Hi, I'm able to display my report on my web application, but after that I can't do anything with the Report object returned by powerbi.embed(...). What happens is that anytime I call a function on the object (setFilters, for example), the Promise never enters the "then" nor "catch" part of my code. It's as if the Promise remained pending forever.

On firefox I get these errors for each function I try to call, which I assume are relevant:

Here is the relevant sections of my code:

<script src="js/powerbi-client/dist/powerbi.js"></script>
<script>
    var models = window['powerbi-client'].models;
    var permissions = models.Permissions.Read;

    const filter = {
        $schema: "http://powerbi.com/product/schema#basic",
        target: {
            table: "Driver",
            column: "DriverID"
        },
        operator: "In",
        values: [<%= driver_id %>]
    };

    var config = {
        type: 'report',
        tokenType: models.TokenType.Embed,
        accessToken: '<%= token %>',
        embedUrl: embed_url,
        id: config_id,
        permissions: permissions,
        filters: [filter],
        settings: {
            filterPaneEnabled: false,
            navContentPaneEnabled: false
        }
    };

    var embedContainer = document.getElementById('embedContainer');
    var report = powerbi.embed(embedContainer, config);

    report.on("loaded", function (e) {
        alert('this is successfully called')
    })

    report.setFilters([filter]).then(function (result) {
        alert("never called 1");
    }).catch(function (errors) {
        alert("never called 2");
    });

    report.getPages().then(function (pages) {
        alert('never called 3')
    }).catch(function (errors) {
        alert('never called 4')
    });

</script>

Thanks for your help!

@powerbi_noob

You shall bind those functions in the "loaded" event, try below sample which works in my test. My understanding is that, before "loaded", the report object is not valid.

 report.on('loaded', event => {
 
  report.setFilters([Filter2]).then(function (result) {
        alert("never called 1");
    }).catch(function (errors) {
        alert("never called 2");
    });

    report.getPages().then(function (pages) {
        alert('never called 3')
    }).catch(function (errors) {
        alert('never called 4')
    });
 
 
});

When calling within report.on ('loaded'), i see that report.getPages() function is not available.

while it is available when calling from outside and observerd that promise is always pending.

var report = powerbi.load(embedContainer, config);

report.on('loaded', () => {

report.getPages().then(function (pages) {
// Retrieve first page.
var firstPage = pages[0];
firstPage.getVisuals().then(function (visuals) {
console.log(visuals);
});
});

});
