Asset bundles WebGL Error + Shader creation failed

Hi,

We started using asset bundles, but got stuck on a release breaking issue.
In the editor and standalone build we can run the game without any issues. However in a Web GL build, the console window returns the following errors:

UnityLoader.js:4
UnityLoader.js:4 ERROR: 0:54: 'bitfieldInsert' : no matching overloaded function found
UnityLoader.js:4 ERROR: 0:55: 'bitfieldInsert' : no matching overloaded function found
UnityLoader.js:4
UnityLoader.js:4 Note: Creation of internal variant of shader 'Vigor/2D/Opaque' failed.

We have built the asset bundles (Build target: Web GL, no compression, copied to streaming assets) and placed our Web GL build on a server.
At this moment, in our standalone build we use the asset bundles locally, meaning we use them from the Streaming assets folder and not downloaded from any server. This works fine. Though, could this be an issue for WebGL? Can we use the asset bundles from the Streaming Assets on a Web GL build, or are these errors caused by this?
If this shouldn't be a problem, what could cause these errors?

Kind regards,
Carsten

 

hello, i have same problem, using Unity 2018.2.14f1

My asset bundles dont work when there is a terrain in there.

Can anybody from UNITY address this. Its serious because terrains dont work and player falls thu the floor ending the game immediately in WebGL.

Thanks
