In an Azure Function a static helper class uses RestSharp 106 like this:

```
public static class InsightlyHelper
{
   private static readonly RestClient RestClient = new RestClient { 
      BaseUrl = new Uri(Environment.GetEnvironmentVariable("InsightlyApiBaseUrl") ?? throw new InvalidOperationException()) 
   };

```

I switched to RestSharp 107 which uses the HttpClient and changed the code to this:

```
public static class InsightlyHelper
{
   private static readonly RestClient RestClient = new RestClient(new Uri(Environment.GetEnvironmentVariable("InsightlyApiBaseUrl")));

```

But this error gets thrown: [Error] Failed to create new SUDB project for insightly project. Error was The type initializer for 'SU\_API.Infrastructure.InsightlyHelper' threw an exception.

I have seen the [Migration guide](https://restsharp.dev/v107/#restsharp-v107)

I am thinking of trying to dependency inject RestClient to this helper class and another similar class, anyone tried that? Or other suggestions appreciated.
