Warning when running on the browser / crash in debug mode

[arximboldi]

I get this warning:

WebGL warning: drawElementsInstanced: type: Invalid enum value 0 (Did you typo `gl.SOMETHINGG` and pass `undefined`?) 

Things otherwise work well. However this warning turns into an assertion in debug builds, which causes the program to crash very inconveniently.

What exactly are you doing to get this warning? Does it happen in one of the examples or can you provide a code snippet that produce this?

Also, what browser do you use?

[arximboldi]

Sorry for the late reply. This is happening to me with all browsers. I am rendering a three_d::Mesh with a three_d::ColorMaterial, using F32 samples and U32 indices.

I am trying to run the examples to see if I can reproduce it there, but I am getting the following error when running npm run serve as suggested in the README.

Note that in spite of the warning, things are working properly for me in release. I would suggest to keep the error as a warning in Debug mode, as panicking is too harsh completely stopping the application and not allowing me to debug other things.

[asny]

Hmm. It's very hard for me to debug this issue. You need to provide a minimal example. Do you use a special 3D model or something?

I am trying to run the examples to see if I can reproduce it there, but I am getting the following error when running npm run serve as suggested in the README.

Seems like the automatically generated files could not be found, did you run all the suggested commands in the Readme?

Pinging @kdoh-dustyrobotics see if he can do it in the future, as he owns now the code-base where this used to (does?) happen.
