RajeevRathor Hi new cabular, Welcome to Casagbic platform.
Solution are here ....
Firstly You need to give project name then click on "Next"
After click on the "Next" then you have to give a project name (Example: com.test.example)
You face this error because after create the project name you click on the ok button. Not on the "Next" button.
Do it now....
Happy Casagbicing 🤝
