OBF.IfcStreamer throws "Error: No scene initialized!"

[keijohyttinen]

Describe the bug 📝

When loading fragmented model from backend, OBF.IfcStreamer throws error "Error: No scene initialized!" when calling

    const tilesLoader = components.get(OBF.IfcStreamer);
    tilesLoader.world = world;
    tilesLoader.url = baseUrl;
    tilesLoader.useCache = true;
    tilesLoader.culler.threshold = 20;
    tilesLoader.culler.maxHiddenTime = 1000;
    tilesLoader.culler.maxLostTime = 40000;
    ....
    await tilesLoader.load(geometryData, true, propertiesData);

Exception

viewer.ts:32 Error: No scene initialized!
    at get scene (index.mjs:6439:13)
    at hi.load (index.js:26996:61)

In addition, after that, there is an exception (not sure whether this is a side effect or root cause(?)):

ModelViewer.js:84 THREE.WebGLProgram: Shader Error 0 - VALIDATE_STATUS false

• Read the docs.
• Check that there isn't already an issue that reports the same bug to avoid creating a duplicate.
• Make sure this is a repository issue and not a framework-specific issue. For example, if it's a THREE.js related bug, it should likely be reported to mrdoob/threejs instead.
• Check that this is a concrete bug. For Q&A join our Community.
• The provided reproduction is a minimal reproducible example of the bug.
