WebGL failing to build in URP.

Hi,

I'm currently running Unity version 2021.2.4f1 and am using the Universal Rendering Pipeline.

Since upgrading my project to URP, I have been unable to build to webGL. Initially I get the following error :

'Shader error in 'Hidden/Universal/CoreBlit': invalid subscript 'positionCS' at Game/Library/PackageCache/com.unity.render-pipelines.core@12.1.1/Runtime/Utilities/Blit.hlsl(92) (on gles)'

However when attempting to build straight after, I get a whole list of errors within the 'Library/Bee' folder, such as :

'Library\Bee\artifacts\WebGL\build\debug_WebGL_wasm\build.js: undefined symbol: __Connect (referenced by top-level compiled C/C++ code)'

I found another forum post that detailed a similar issue, however I could not find any resolution to the problem.

I'm wondering if anyone has any experience with this issue or who might be aware of a fix? I've tried updating the project to numerous later versions, however this has not solved the issue.

Thank you!

 

Have you tried updating to the latest 2021.2 and updating your packages to the latest available version?

 

Hi DevDunk, Thanks for your response. I've tried updating my project to that latest version, 2021.2.11. This unfortunately didn't seem to resolve the issue. As far as I can tell all my packages are up to date.

I also tried to downgrade to an earlier version of 2021.2.2, however this didn't help either.

I also upgraded another project (that was previously working and using version 2020.3.8f1) to 2021.2 and this seems to have caused the same issue as mentioned in my previous posts.

 

Hi eHaka,

Thanks very much for your response. I've changed the typo but whenever I go back into Unity the shader seems to return back to its original state, changing the line of code that I've amended back to it's original state.

 

I've amended the typos now, but unfortunately I still seem to be unable to build, and am getting over forty errors relating to the 'Bee' folder. The first of these errors states :

Library\Bee\artifacts\WebGL\build\debug_WebGL_wasm\build.js: undefined symbol: __Connect (referenced by top-level compiled C/C++ code)
UnityEditor.BuildPlayerWindow:BuildPlayerAndRun ()​

 

It seems that these issues are being caused by a package within my project that seems to be causing issues when exporting to webgl. I've not found a fix yet but found this forum post to be potentially useful.

 

Thank you eHaka, I've tested that out and the issues relating to the shaders seem to be fixed.

 

Any updates on this? There has been updates since this issue was noticed, yet they still haven't fixed it in the latest 12.1.6 version.

 

Bump. Unity 2021 just got in to LTS with this error still happening, creating our own package isn't a real solution. I mean, are we expected to just wait for a fix and not be able to create a build until then?
Is there an ETA for this fix?

 

Experiencing this issue as well. Would be great if known solution makes it into official package release.

 

Just got this when building for Android

And I already removed Opengles2 from GraphicsAPI than WHY ?
Unity 2021.2.19f1

Why why why, we always got this problems with unity.

 

for me, it's solved by not using the "build and run" option, just use the "build" button and deploy apk manually.

 

I changed back to built-in render pipeline so I could build my project again. I got the same error when building to webgl, but changing the render pipeline solved.

 

Is there an ETA on when this fix will be released?
