I've set up a Docker container using both Flask and MongoDB to make a web service. However, when it's time for MongoDB to set up, this batch of errors keeps appearing:

mongodb exited with code 14
For reference, here's my docker-compose:
version: '2'
services:
mongodb:
image: mongo
restart: always
container_name: mongodb
ports:
- 27017:27017
volumes:
- ./mongodb/data:/data/db
flask-service:
build:
context: ./flask
restart: always
container_name: flask
depends_on:
- mongodb
ports:
- 5000:5000
environment:
- "MONGO_HOSTNAME=mongodb"
Since I made it always restart, the database naturally does that, but I can't exactly figure out how to resolve this issue. From reading the errors, it seems like there's a problem with either permissions, or the WiredTiger installation. This also produces many zero-byte WiredTiger.wt.# files, one per attempt.
And here's also the Dockerfile:
