Hello everybody

Tangram v0.20.1

I’ve got a strange connection error:

TO REPRODUCE THE ISSUE, FOLLOW THESE STEPS:
I’ve used Tangram with pbf data from by my own tile server. The server works well with L.VectorGrid plugin. CORS headers are on

RESULT:
The connection error as above.

EXPECTED RESULT:
Connection established.

Здравствуйте!

Оригинальный исходный код: https://github.com/Mixturka613/Lesson-ThreeJS
Поменял только путь к своей модели.

Выдает ошибку

Error: [object ProgressEvent]

Модель не отображается.

Функция загрузки модели выглядит так:

let loader = new GLTFLoader();

             

                loader.load('./model/test.glb', gltf => {
                scene.add(gltf.scene);
                }, 
                    function (error) {
                        console.log('Error: ' + error)
                    }
                )

При этом, на сайте gltf.report например, модель открывается в редакторе и видна.
