HEAPU8 is undefined

[GenghisChen]

Hello

When building and running the app in a browser according to the posted instruction, the following error appears:
TypeError: can't access property "buffer", module.HEAPU8 is undefined

The module that is passed into the constructor of wrapper.js does not have the HEAPU8 property.

Built using the following Dockerfile:

FROM ubuntu:latest
WORKDIR /app
RUN apt update && apt install -y git cmake make python3 xz-utils npm vim
RUN git clone https://github.com/emscripten-core/emsdk.git
SHELL ["/bin/bash", "-c"]
RUN cd emsdk && \
	./emsdk install latest && \
	./emsdk activate latest
RUN git clone https://github.com/WebCryptomining/WebRandomX.git
WORKDIR /app/WebRandomX
RUN sed -i 's/Your Server IP/127.0.0.1/g' src/js/job.js
RUN source /app/emsdk/emsdk_env.sh && \
	mkdir build && cd build && \	
	emcmake cmake -DARCH=native .. && \
	make && \
	emcmake cmake -DARCH=native -DTESTS=true .. && \
	make
RUN npm install

Please advise
Thanks
Chen
