Unable to test "My First Project" on Google actions page and google assistant

I followed all the steps shown in the lecture as it is, but after uploading my project when I start the test on Google Actions page, i get the error:-

Can’t test it on google assistant either (some other project is opening in google assistant).

Please someone help as soon as possible.

@khandenathparth Please change the name of your project. ‘My first project’ becomes a reserved word to avoid duplications.

Thanks @ashwin.salgaocar. This resolves my query. I feel the thing you told me must be put in the lectures as well.
