Unable to convert gltf to glb

[liinnjohansson]

I am trying to convert a gltf-model to glb with the latest Node version (17.9.0). I get the error below when running this command line in directory containing the gltf-model:

gltf-pipeline -i sphere.gltf -o sphere.glb

Error at new RuntimeError (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf- pipeline\node_modules\cesium\Build\CesiumUnminified\Cesium.js:7121:13) at fileURLToPath (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\FileUrl.js:38:11) at readFile (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\readResources.js:148:24) at readResource (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\readResources.js:114:10) at readImage (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\readResources.js:73:10) at C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\readResources.js:55:31 at Function.ForEach.object (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\ForEach.js:44:21) at Function.ForEach.topLevel (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\ForEach.js:63:18) at Function.ForEach.image (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\ForEach.js:202:18) at C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\lib\readResources.js:54:15 at tryCatcher (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\node_modules\bluebird\js\release\util.js:16:23) at Promise._settlePromiseFromHandler (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\node_modules\bluebird\js\release\promise.js:547:31) at Promise._settlePromise (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\node_modules\bluebird\js\release\promise.js:604:18) at Promise._settlePromise0 (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\node_modules\bluebird\js\release\promise.js:649:10) at Promise._settlePromises (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\node_modules\bluebird\js\release\promise.js:729:18) at Promise._fulfill (C:\Users\flisa\AppData\Roaming\npm\node_modules\gltf-pipeline\node_modules\bluebird\js\release\promise.js:673:18) { message: 'Expected path.protocol to start with file:' }

There is no problem to open and view model in a 3D-displayer.
I am also using latest React version in this project.

Any suggestions?

It seems like it's unable to load a uri in your gltf. Based on the trace it's hitting this error:

  if (path.protocol !== "file:") {
    throw new RuntimeError("Expected path.protocol to start with file:");
  }

Does this give any ideas? Could you post your gltf?

Thanks for the reply!
That sounds about right, I'll check with my colleague who made the model.

But if you have the time, it would be great if you could have a look as well!

Thanks for posting the glTF. The problem is here:

"images": [{"uri": "C:\\Users\\46767\\Desktop\\web3d\\Textur.png"}],

Try using a relative path instead.

Great!
Now it works perfectly, thanks!
