## Feature(s) impacted

Setup

## Observed behavior

Hey there - I recently installed forest as a Rails framework setup. However, when I boot up my server I get a `ActiveRecord::ConnectionNotEstablished` error. However, I’m using MongoDB as the database.

## Expected behavior

Successful connection

## Failure Logs

```

Is the Rails framework setup compatible with Mongodb as a database? Ideally, I would want to setup via the framework vs a microservice.

Hello @matthewblack. 👋 Welcome to our community

Our rails agent is currently not compatible with mongodb.  
The only solution is to use our structure microservice.

I pushed your request to our ProductBoard.  
Please come back to us if you need help.
