Hi @anon34731316,

Can you give a little bit more context ?

What happened ? Do you have an issue during the `lumber generate` ? Or after ?

Hey @anon62739609, thanks for your prompt reply.

Actually I finally succeeded connecting my DB properly and creating for Forest project 🎉  
I just did not declare the SRV in the “advanced db settings” so my db url was wrong.

I just have one thing weird: my collection are almost empty (they contain just their id).  
I noticed that I had on my terminal some warning info when my project was created:

Is it the reason why my collections are empty?  
Do you know how can I fix them?

Like the logs says, `mapReduce` is not authorized on the free tier of Mongo DB Atlas. Sadly we use this function to generate automatically your models right now. SO you’ll have to create your models manually. I hope this [guide](https://docs.forestadmin.com/documentation/reference-guide/models/enrich-your-models) can help you.

Ok I’ll take care of it myself then.  
Thanks 🙏
