How catch error 409 (path/not_found/.) when try download file?

[RodFX]

Use a Dropbox-sdk.min.js

<script src="http://bootboxjs.com/bootbox.js"></script>
<script src="https://unpkg.com/dropbox/dist/Dropbox-sdk.min.js"></script>
 

dialog.modal('show');
var ACCESS_TOKEN = '<?php echo DROPBOX_ACCESS_TOKEN;?>';
var dbx = new Dropbox({
    accessToken: ACCESS_TOKEN
});
dbx.filesDownload({
        path: "/" + id
    })
    .then(function(data) {
        dialog.modal('hide');
        if (data.fileBlob != null) {
            var downloadUrl = URL.createObjectURL(data.fileBlob);
            var downloadButton = document.createElement('a');
            document.body.appendChild(downloadButton);
            downloadButton.setAttribute('href', downloadUrl);
            downloadButton.setAttribute('download', data.name);
            downloadButton.click();
            window.URL.revokeObjectURL(downloadUrl);
            document.body.removeChild(downloadButton);
        } else {
            bootbox.alert({
                message: "Error " + id + " dont exist."
            });
        }
    })
    .catch(function(data) {
        dialog.modal('hide');
        bootbox.alert({
            message: "Fail " + id + " wait"
        });

    });

If the file isn't found, your catch block should get run, with the data variable containing the error information. Is that not running for you?

[RodFX]

Is not running the cath.

Look:

[Greg-DB]

Thanks! We'll look into it.

[RodFX]

How catch the error ritht now?

[RodFX]

I try with:

window.onerror = function() {
};

[Greg-DB]

This is a bug with the library itself, and not something you should have to handle yourself. We're looking into it, but I don't have a timeline for a fix right now.

[RodFX]

How can i help you?

[Greg-DB]

We're able to reproduce the issue, so we shouldn't need any more information from your side. Thanks though!

[Greg-DB]

This should be fixed and no longer throw a `DOMException` as of v3.0.0.
