Does HTML5 export work for Unreal 4-27 and 5?

I am recently working on packaging UE4 projects into HTML5, and I hope to be able to use the 4.27 version of the engine.
Is anyone running normally on 4.27?
I tried, but there was a problem when packaging that the oodle format was not supported, so I turned off the plugin. After that, the package succeeded, but the screen was black at runtime.
Check the log and analyze, may be 4.27 does not support SP_OPENGL_ES2_WEBGL and
replaced by SP_OPENGL_ES3_1_ANDROID ? Or some webgl errors such as “invalid_operation: drawarrays: no buffer is bound to enabled attribute”?
