jest-mongodb | Jest preset for MongoDB in-memory server | Runtime Evironment library

I have an error that's only happening in my Github Actions workflow (when I run my Jest script locally, it's fine). I've only found this SO answer and this one but error still persists. Any thoughts on what to check next?

Here's the error:

I am not getting 100% of coverage for the file below and I cannot figure out why this is happening....

Focus of the question: understand why Jest is not considering my tests that cover the lines that Jest complains about not being covered.

Jest complains about these lines of code: 26-27,33-34,38-39,45-46, but these lines are covered, as it can be seen on the test file that I will paste below the production file.

26-27:

I created a docker image which stores an npm project. The npm project has an npm script which runs tests. I use Gitlab for CI/CD where I want to define a job which will pull my image and run the npm script. This is the .gitlab.yml:

As I'm introducing authentication for my MongoDB instance in Docker, I ran into problems which are probably related to the way agenda.js tries to connect to MongoDB, as the connection string invokes successful logs for mongoose connecting to the DB, therefore I assume the string should be valid.

Everything worked until I changed the connection string to use authentication. I verified the users are properly created in the database and also tried variations of the connection string and deleting/installing node modules.

Following output I get upon running docker-compose up:

I am building tests for my node/express controller methods and using @shelf/jest-mongodb. I am creating a document first, and then when I try to find that I have to run find twice from model in order to get the results. It should get the results in the first find instead.

test.js

i have a project that uses jest, i can run jest with npm test and it works if i dont set a preset.

I need the preset @shelf/jest-mongodb, and i get the error that is in the title of this post.

Here is my jest.config.js:

I’m learning to create RestAPI’s using NodeJS and MongoDB from this tutorial, and from the repo they have provided[which has quite a lot of updates from the post], I further modified it to do UnitTesting of my Mongo server with Jest and SuperTest.

The major changes I’ve made to the repo before adding mine is:

Move the listen logic to a start.js, while in package.json make this the main file
