Now, every project display me the same message: This project cannot be deleted because it is connected to a Dialogflow agent. Please delete the agent in Dialogflow first. But I have already deleted every agent that was related to the project. I have already tried on firebase but display this: A lien to prevent deletion was placed on the project. Remove the lien to allow deletion. I getting mad, please can someone help me? Thank you very much
