Failing to convert SVG to EPS via shell execution - Beyond the Basics

Hello. I am experiencing an issue while converting an SVG to an EPS via shell execution from a NodeJS script. Inkscape 0.92.2 running in a Docker container. The issue only happens when the SVG contains a reference to a PNG, e.g. <image xlink:href="path/to/png" /> while running via shell execution in NodeJS. This issue does not appear when running the same command directly in the container. Shell command being run: inkscape input-file.svg -E output.eps --export-ignore-filters --export-ps-level=3

When run by NodeJS, inkscape prints this to stderr:
