Glitch error: project load without .env archive

I have a problem loading project: ‘!/ruby-purrfect-lunch?’. This is for MongoDb and Mongoose challenge.
The problem: when I charge the glitch url, I see an error: ‘An error occurred when trying to create this project, please try again later.’. And later, I see the project charged but without .env archive loaded. ¿Can you help me, please?
