Custom visual external Javascript in PowerBi Desktop Issue

[etiskapp]

Hi,

We have custom visual component taht needs to use external javascript loaded using the script tag.
Here is an extract from our source code :
private scriptsUrl: string[] = [
"//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js",
"https://api.bimsync.com/1.0/js/viewer.js"];

private loadNext = (resolve, reject) =>{
const scriptsUrlElement = this.scriptsUrl[this.loadCount];
let htmlScriptElement = document.createElement('script');
htmlScriptElement.src=scriptsUrlElement;
htmlScriptElement.crossOrigin = "anonymous";
document.body.appendChild(htmlScriptElement);

htmlScriptElement.onload = () => {
console.info("Viewer scripts loaded");
this.loadCount++;
if (this.loadCount >= this.scriptsUrl.length) {
resolve();
}else{
this.loadNext(resolve, reject);
}
};

htmlScriptElement.onerror = (message, url, line, column, error) => {
console.info("Viewer scripts error:" + error);
reject({message,url,line,column,error});
};

}

On web (PowerBi service) it works perfectly but on powerbi desktop we only have an object error (in the onerror) :
{
trusted:true
}

Is there a way to debug this on powerBI desktop or anything we should do ?

You may take a look at Adding external libraries and visit Custom Visuals Development Discussion for assistance.

We can't use the "adding external libraries" because the bimsync library can't be added as a node module.

I'll repost it on the Custom Visuals Discussion.
