I’m working with Phoenix 1.7 and Docker fails at the step RUN mix.assets.deploy when deploying to fly (mix assets.deploy) works locally.

I installed the package with npm install @mapbox/search-js-web --save it’s listed in 'assets/ package-lock.json. Then I'm importing it from assets/js/maps.jswith:import { autofill, config } from ‘@mapbox/search-js-web’` seems to be standard JS stuff. What am I missing?
