Resolution Note:
Thank you for reporting a bug to Unity.
According to the Editor.log file attached, there is an undefined method being imported. The log shows that method "SelectSingleFile" has no function definition but is trying to be added to the build.js file. To prevent this, ensure that all imported javascript plugin methods have a corresponding definition in the .jslib plugin.
Build error:
"Building Library\Bee\artifacts\WebGL\build\debug_WebGL_wasm\build.js failed with output:
error: undefined symbol: SelectSingleFile (referenced by top-level compiled C/C++ code)
warning: Link with `-s LLD_REPORT_UNDEFINED` to get more information on undefined symbols
warning: To disable errors for undefined symbols use `-s ERROR_ON_UNDEFINED_SYMBOLS=0`
warning: _SelectSingleFile may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library"
Referring to JavascripManager.cs line 16 & 17 SelectSingleFile is not referenced or found anywhere else in the project while the others are meaning theres no definition. A successful build can be achieved via commenting out those two lines or creating a function definition with the other javascript methods
