I see a potential cause of the problem. I don't quite follow your notation
in the last part of the code (after let a: object), but I see:
"other_params": `client=${credentials}&sensor=false&channel=${client}&
libraries=geometry,visualization,places,drawing `,
This would be a problem since the new loader is not yet handling the
other_params parameter. I am actually making a change to support it now,
because it turns out this is the cause of some internal problems as well.
Also, this code makes me wonder:
var script =
<HTMLScriptElement>document.createElement("script");
script.src = "
https://www.google.com/jsapi?callback=MapUtil.googleLoaderCallback";;
script.type = "text/javascript";
document.getElementsByTagName("head")[0].appendChild(script);
MapUtil.loadApiCallback = callback;
Since you add the script tag that includes the
callback=MapUtil.googleLoaderCallback, but I don't see where you have
defined MapUtil.googleLoaderCallback, unless it is the definition of public
static googleLoaderCallback(), which would have to be static methods of
MapUtil.
But since there are multiple callbacks in your code, I am not sure which
callback you are referring to. I see:
if (MapUtil.loaded) { callback(); }
jsapi?callback=MapUtil.googleLoaderCallback
MapUtil.loadApiCallback = callback;
google.load(... {"callback": () => {}})
MapUtil.loadApiCallback();
And are you saying the callback is not called at all, or that it fails for
some reason when it is called?
