## Expected behavior

Tried to use the new Rails installation method but we immediately come up against a 500 server error. Looks like the server is receiving a `rendering_id` but expecting `renderingId` ?

## Actual behavior

The admin portal errors and in the network panel you can see why (see below).

## Failure Logs

According to the network panel we can see the forestadmin API says:

```javascript

{
    "errors": [
        {
            "status": 500,
            "detail": "Authentication request must contain a renderingId"
        }
    ]
}

```

Server logs:

```javascript
app | Started POST "/forest/authentication" for at 2021-02-25 08:52:32 +0000
app | Processing by ForestLiana::AuthenticationController#start_authentication as */*
app | Parameters: {"rendering_id"=>"83806"}
app | Completed 500 Internal Server Error in 2ms (Views: 0.3ms | ActiveRecord: 0.0ms)

```

## Context

Please provide any relevant information about your setup.

- Package Version: forest\_liana 6.0.0

Hi @benwhite !  
There are issues with de v6 for now, we are working on them !  
I can’t reproduce your error, the `rendering_id` should be parse into `renderingId` by the ActionController if I’m not mistaken 🤔  
I guess you followed [this](https://docs.forestadmin.com/documentation/how-tos/maintain/upgrade-notes-rails/upgrade-to-v6) documentation ?

Ah okay. I followed the images documentation here which is why I ended up with 6.0.0

You can follow the upgrade note I shared to try and make it work 🙂  
We are working on fixing the project creation on v6 (it doesn’t create the required environment variables).

Hello,

I have exactly the same error, but I’m using version 7.6.7 of the forest-liana gem, and just created the project by following the instructions after signing up.

Any idea on how to fix this?

thanks
