Parse-Server Docker-Container custom volume saved data not working - docker

Question

I am new to parse-server and to docker world, and I think that either I did not understand this properly or it is not working. Sorry if this will come as a stupid question.
So from docker documentation, I understand that if I want to bind a folder location to my docker location I have to do something like this.
volumes:
- /host/path/to/folder:/docker/path/to/folder
But the thing that I am missing is that after I create all my docker and I bind the volume paths like this when I am adding new rows into my MongoDB database I will have nothing saved into those folders. Can anyone explain to me what I am doing wrong?
Basically, I am trying to save all my changes from MongoDB and the server into a local folder.
My docker-compose:
version: '3.9'
services:
database:
image: mongo:6.0.1
environment:
MONGO_INITDB_ROOT_USERNAME: admin
MONGO_INITDB_ROOT_PASSWORD: admin
volumes:
- ./data/mongodb:/data/mongodb
server:
restart: always
image: parseplatform/parse-server:5.2.5

- PARSE_ENABLE_CLOUD_CODE=yes

links:

volumes:
- ./data/server:/data/server
dashboard:
image: parseplatform/parse-dashboard:4.1.4
ports:
- "4040:4040"
depends_on:
- server
environment:
- PARSE_DASHBOARD_APP_ID=COOK_APP
- PARSE_DASHBOARD_APP_NAME=COOK_APP
- PARSE_DASHBOARD_MASTER_KEY=MASTER_KEY_1
- PARSE_DASHBOARD_USER_ID=admin

- PARSE_DASHBOARD_ALLOW_INSECURE_HTTP=true
- PARSE_DASHBOARD_SERVER_URL=http://localhost:1337/parse
volumes:
- ./data/dashboard:/data/dashboard
UPDATE:
After I've checked your response regarding ./data/mongodb:/data/db is working just partially. In a sense that I have these 2 cases.
If I will use it like this data/mongodb:/data/db without that . in order to save that data into my root directory, then everything is working fine. But I would like to save it in my local directory where all the projects will be.
So if I am doing as you said ./data/mongodb:/data/db in order to save it into the local directory my MongoDB is not going to star and I will get this error message for some unknown reason.

Any idea why?

If you check the "where to store data" section of the mongo image documentation (https://hub.docker.com/_/mongo), you will see that, inside the container, mongo actually saves the data in the folder /data/db (and not /data/mongodb). So you will have to bind it:
volumes:
- ./data/mongodb:/data/db
