I deploy simple oak app on deno deploy, my experience

I deploy https://github.com/elycheikhsmail/deno-oak-helloword/blob/main/server.ts in https://github.com/elycheikhsmail/deno-oak-helloword repo using deno deploy platform it work on https://exciting-kingfisher-72.deno.dev/ , you can see the code .
deno deploy requier client permission to access to his reposetory, my deploy failed befor I give the permission.
I try to deploy this simple by giving the url https://github.com/elycheikhsmail/deno-oak-helloword/blob/main/server.ts to deno deploy but it failed with error message tell me I have error in line 7 but this error dosn't exist. the developer must hand not found situation.
