Verifying the app on google cloud

Hey all, i have been recently trying to get my app verified. However it has been a pain, i have been getting errors every time about different things, I was getting this error recently while verifying my site https://pavetheway.ai/ . I fail to understand what is required to be done for this. I am trying to get verification for using google calendar api for the crud operations on the public calendar and nothing else. Just using 5 scopes on this. How should i proceed ? Would appreciate any pointers.
