Angular - Property ' ' does not exist on type ' '

I'm a beginner to angular and am taking an online course on edx. In one of the tutorial labs, I am learning how to use the HttpClient.

ngOnInit() {
   this.GitSearchService.gitSearch('angular').then( (response) => {
    alert("Total Libraries Found:" + response.total_count);
   }, (error) => {
    alert("Error: " + error.statusText)
   })
 }
 title = 'app is functional!';
}

It says total_count does not exist on type unknown, but in one of the imports, I have "total_count": number

Problem is that the response variable doesn't have a type.
You can fix that in different ways, some cleaner, some less.

An unclean way, for example, would be to workaround the typing

alert("Total Libraries Found:" + response['total_count']);

A more clean way would be to provide a type to the response

this.GitSearchService.gitSearch('angular')
  .then( (response : MyAwesomeType) => { your code } )

in this case, MyAwesomeType is expected to be a type that has the property total_count
