Docker permission issues with Yarn

Question

I'm having the following issue when trying run my container:

psa-web    | Error: EACCES: permission denied, open '/root/.config/yarn'
psa-web    |     at Object.openSync (node:fs:495:3)
psa-web    |     at readFileSync (node:fs:396:35)

psa-web    | npm ERR!     /root/.npm/_logs/2021-01-29T09_01_06_202Z-debug.log

version: "3"

services:
  psa-web:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: psa-web
    restart: always
    volumes:
      - ./:/usr/src/app
      - /usr/src/app/node_modules
      - /usr/src/app/.next
    ports:
      - "${NEXT_PUBLIC_APP_PORT}:${NEXT_PUBLIC_APP_PORT}"

Here's my Dockerfile:

FROM node:15.5.0-alpine3.10

RUN apk add --update --no-cache 
    python 
    make 
    g++

WORKDIR /usr/src/app

# install and cache app dependencies
COPY package.json /usr/src/app
COPY yarn.lock /usr/src/app

RUN yarn install --frozen-lockfile


EXPOSE 3003
CMD ["npm", "run", "dev"]

Here's also the package.json file, for better context. That's were I automatically run yarn install before starting my next application on dev, and the potential source of this error.

package.json

"scripts": {
    "dev": "yarn install && next dev",
    "build": "next build",
    "start": "yarn install && next start",
    "lint": "eslint .",
    "update:shared-deps": "yarn upgrade --scope @project-stock-alarm --latest",
    "lint:fix": "eslint . --fix"
  },

Any ideas of what I'm doing wrong?

If I do a sudo yarn install and a sudo chown -R root it solves the issue, but this is not best practice.
