Issue: ERROR [MongooseModule] Unable to connect to the database, getting backend to start

[mykelbengineer]

When I start the backend by

cd backend

npm run start:dev

I get the following output

Am I missing a node module or didn't follow an instruction?

Okay, after realizing you are not the author of the code, but instead just forked it, I tried to replicate the issue. Simple answer is that they did not provide the .env.example files therefore without the lacking env files and the examples you didn't create a .env in backend folder with the specified values that are being used.

Right! I’m just trying to review the code and without much assumption, I was hoping it was something as easy or simple as you have pointed out.

Hopefully they can add a sample env. Thanks for your comments, they are very insightful. Hadn’t thought about that

@mykelbengineer thank you for putting eyes on this! @AmadeusMoon as well!

So I believe we have things at least potentially sorted on this front. We will get the .env.example file up shortly! Thank you both for taking the time to add issues and bring things forward to us, it's greatly appreciated!

We worked this morning on getting registration fixed and believe we found a solution. Had some CORS issues, but those seem to be solved with our latest release :)
