Failed to generate resource

[johnkhansrc]

Hello, I am interested in your project.

In order to test I generated a Model.
I then wanted to generate an API resource and I encountered a somewhat obscure error.

➜  cqrstest git:(main) ✗ bin/console make:ddd:resource  

 The name of the model class to create the resource for (e.g. Customer). Model must exist already.:
 > Customer

 Which base path should be used? Default is "src/" [src/]:
 > src/Customer/


                                                                                                                        
 [ERROR] Unknown config flavor:

What is my mistake?
