Get request to Mongodb returns empty response - on the server, same code on localhost works as expected

Trying to Dockerize a Node Express Mongo app, running locally front and backend communicates fine. In Docker both front and back servers starts. The landing page of the app loads up but getting and creating data fails.

Connection to Mongo is below - port 27017 is already used by another container so I expose port 27027

mongoose.connect(
  "mongodb://mongo:27027/report",
  { useNewUrlParser: true, useCreateIndex: true }
);

In the dockerfile

FROM node:10
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm install -g nodemon
EXPOSE 5600
CMD [ "npm", "run", "dev"  ]

Docker-compose

version: '3'
services:
  app:
    build: ./
    container_name: report-node
    restart: always
    working_dir: /usr/src/app
    environment:
      NODE_ENV: development
    ports:
      - 8880:8080
    volumes:
      - ./:/usr/src/app
  mongo:
    container_name: mongo
    image: mongo
    ports:
      - 27027:27017
    volumes:
      - ./data:/data/db

the get request to retrieve data is

const API_URL = 'http://192.168.141.175:5600';

export default {
    getReports() {
        return ezFetch.get(`${API_URL}/api/report/list`)
},
