Hi @DOEHOONLEE
This blob:nodedata: looks weird. Like @RaananW said, your code for generating object url might not be correct.
Can you try the following approach to avoid generating object url?
// Read raw binary content from your model file
const glbRawContent = fs.readFileSync('<YOUR_FILE_PATH>');
// Generate base64 string of your model
const base64Content = Buffer.from(glbRawContent).toString('base64');
const base64ModelString = `data:base64,${base64Content}`;
// Import Mesh from base64 string instead from url
BABYLON.SceneLoader.ImportMesh('', '', base64ModelString, scene);
