Frontend HTML5 Failed (Missing PhysX)

I’m trying to build any project to HTML5. I’m following instructions from here:

I’m also using the Unreal Documentation.

But UnrealBuildTool.txt log error:

ERROR    root: C:\Users\cristian studio\Documents\GitHub\UnrealEngine\Engine\Source\ThirdParty\PhysX\PhysX-3.3\lib\HTML5\LowLevel.bc: No such file or directory ("C:\Users\cristian studio\Documents\GitHub\UnrealEngine\Engine\Source\ThirdParty\PhysX\PhysX-3.3\lib\HTML5\LowLevel.bc" was expected to be an input file, based on the commandline arguments provided)

There’s no folder HTML5 inside UnrealEngine\Engine\Source\ThirdParty\PhysX\PhysX-3.3\lib

Any ideas? Is that a bug?

After all it was my fault. It was missing the file dependency.
