Mongo shell not showing content

I have created a web app with nodejs and express. I am using mongolian for connecting with mongo db.

Although i am getting right data in my GET requests, when i try to see the data in the shell, i do not see any.

Here is the log:

and for the shell:

and it shows no output.

i noticed connecting to: test in the shell. i gave parameters like dev, prod in the command line like mongo.exe prod but nothing worked. All of them shows the dbs and messages but not content.

What am i doing wrong ?

You have a spelling mistake in your collection name. You have messsages with three "s" characters.

I'm assuming that this is simply a "typo" in the shell.Muscle memory made you type the "correct" spelling of "messages" even though the actual collection name has errors in it.

Mongo will allow you to switch to/ use databases, collections even if they do not yet exist. The moment you try to insert a document - the structure is created.
