tar: bundle: Cannot mkdir: Permission denied (possible issue with docker image)

[programthis]

I am using a custom docker image which I suspect may be the cause of this error (possibly a permission issue?). I've pasted it below:

FROM zodern/meteor:latest

USER root
RUN apt-get update && apt-get install -y \
	graphicsmagick \
	graphicsmagick-imagemagick-compat \
&& apt-get clean \
&& rm -rf /var/lib/apt/lists/*

USER app

Meteor version: 2.7.3
