Need help with the compilation issue with the docker mendix buildpack

Experts,      I have a mendix project for which I created the deployment package. I am just trying to build and run the mendix app on the docker setup. I installed the docker on windows and the docker mendix buildpack. I followed the instructions as below to build my app (“Test-main”):   docker build --build-arg BUILD_PATH=C:\Users\guda\Documents\Mendix\Test-main --build-arg ROOTFS_IMAGE=mendix/rootfs:bionic --build-arg CF_BUILDPACK=v4.9.4 --tag mendix/mendix-buildpack:v1.2 . I am getting the below compilation error. Tried a bunch of times but running into the same issue. Appreciate if one of you can help me get past this issue. NOTE: I gave the mendix project root folder as my BUILD_PATH.    Sending build context to Docker daemon  2.057GB Step 1/26 : ARG ROOTFS_IMAGE=mendix/rootfs:bionic Step 2/26 : FROM ${ROOTFS_IMAGE} AS builder  ---> f178c28cb197 Step 3/26 : ARG BUILD_PATH=project  ---> Using cache  ---> caec8a35662e Step 4/26 : ARG DD_API_KEY  ---> Using cache  ---> 1eee282a00d3 Step 5/26 : ARG CF_BUILDPACK=v4.5.8  ---> Using cache  ---> 7acd28320700 Step 6/26 : RUN mkdir -p /opt/mendix/buildpack /opt/mendix/build &&    echo "CF Buildpack version ${CF_BUILDPACK}" &&    curl -fsSL${CF_BUILDPACK}.tar.gz | tar xz -C /opt/mendix/buildpack --strip-components 1 &&    chgrp -R 0 /opt/mendix &&    chmod -R g=u  /opt/mendix  ---> Using cache  ---> 4f420b2cca96 Step 7/26 : COPY scripts/compilation scripts/git /opt/mendix/buildpack/  ---> Using cache  ---> 5490bace7a9a Step 8/26 : RUN chmod +rx /opt/mendix/buildpack/bin/bootstrap-python && /opt/mendix/buildpack/bin/bootstrap-python /opt/mendix/buildpack /tmp/buildcache  ---> Using cache  ---> 21be1635bf6b Step 9/26 : ENV PYTHONPATH "$PYTHONPATH:/opt/mendix/buildpack/lib/:/opt/mendix/buildpack/:/opt/mendix/buildpack/lib/python3.6/site-packages/"  ---> Using cache  ---> ea2ffcaa2fba Step 10/26 : RUN mkdir -p /tmp/buildcache /var/mendix/build /var/mendix/build/.local &&    chmod +rx /opt/mendix/buildpack/compilation /opt/mendix/buildpack/git /opt/mendix/buildpack/buildpack/ &&    cd /opt/mendix/buildpack &&    ./compilation /opt/mendix/build /tmp/buildcache &&    rm -fr /tmp/buildcache /tmp/javasdk /tmp/opt /tmp/downloads /opt/mendix/buildpack/compilation /opt/mendix/buildpack/git &&    ln -s /opt/mendix/.java /opt/mendix/build &&    chgrp -R 0 /opt/mendix /var/mendix &&    chmod -R g=u /opt/mendix /var/mendix  ---> Running in a13f6004e48d INFO: Mendix project compilation phase...

It seems like your Dockerfile has a missing step. After step 7, the Dockerfile is supposed to copy your project folder into the build container, per this line:

Is your script missing this step? I would expect it to be logged as step 8, but it seems to be missing this step and moving onto the ‘chmod’ command after.
