the other issue may be a CORS issue, you can verify this by opening the browser console and looking at what errors are generated when you run the tests
Maybe its your quotation marks. Try using " (two straight ones) instead of the backward/forward quotes. When i pasted your code it didn’t do the color highlighting right until I changed that anyway.
I had the same response from the tutorial page so, i right clicked on the page > Inspect > Console and found 2 errors. Then i saw on the 1st error that the test is expecting to find the package.json file inside the “_api” folder “localhost:5500/_api/package.json“ and not the one you start with which is on the root of the project eg: “boilerplate-npm/package.json“;
