Questions for Step 2

For step 2:

2. Request a (random: see #3) variant
   Make a fetch request to one of the two URLs, and return it as the response from the script.

I am wondering what type of response should we send back? Should it just be the plain text response from one of the two URLs? (aka HTML source code)

Permission Denied during wrangler config

I created an API token using the "Edit Cloudflare Workers" template, but when I entered the API token key, I got this error message:
Validating credentials...
Error: Permission denied (os error 13)

Does anyone know how to solve this issue?

Thanks

Wrangler unable to be installed

I've used NPM to install wrangler but every time I try to use the CLI, I get the following message:

      throw `You have not installed ${this.name ? this.name : "this package"}`;
      ^
You have not installed wrangler

I'm not sure how to fix this. I tried searching for a solution online and in the wrangler docs but couldn't find anything. What should I do?

3rd requirement is unclear

I didn't fully understand the requirement "3. Distribute requests between variants".
So, I don't have to show different pages to a single user every time(as it's said "when a client makes a request to the Workers script, the script should roughly return each variant"), so I don't have to use cookies for this. Is seems like it's enough just to remember user and count each of 2 urls, or I could use round-robin method, 'cause each of these will give 50% probability. I know that using cookies is extra-credit task "2. Persisting variants
", but I'd like to do both ways :)

CORS header ‘Access-Control-Allow-Origin’ missing

Hey guys, when I try to run a simple fetch to that URL, I get this error back (bottom). Is there anyone else experiencing the same issue? I've been doing some research on it, but it's still not clear to me how to fix it

code:

fetch("https://cfw-takehome.developers.workers.dev/api/variants" { /* properties here */ });

error:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cfw-takehome.developers.workers.dev/api/variants. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

Do we need to redirect the page?

For this requirement

3. Distribute requests between variants

I am wondering what type of actions should we take. Should we simply redirect the page or fetch the content of the variant page and return that as a response?

I am currently working on the extra credit and I realized that with redirecting we probably can't do this task.

For each variant page, there are a number of items on the page that can be customized. Try changing the following values inside of the variant, adding your own text or URLs:

So what is the expected action?

TypeError: Failed to execute 'fetch' on 'Window': parameter 2 ('init') is not an object.

Please can anyone tell me what this error is about and how to resolve it? I am new to Javascript so may this is a basic mistake or error.
My code showing error:
fetch('https://cfw-takehome.developers.workers.dev/api/variants', method="no-cors").then(response => response.json()).then(json => console.log(json))

Thanks:)

Cookies can be written but not read from a serviceWorker

Extra Credit 2 should be removed or updated with a possible solution because headers are stripped from the request before it gets to the serviceWorker's handler. Cookies can be set but not read from the serviceWorker. localStorage and other storage solutions are not accessible from the serviceWorker either. In conclusion, persistence is not achievable at the moment.

The requirements in a nutshell

Hello!
So as far as I understand when the user visits the root URL of the app, it should either load variant 1 or variant 2, There is no home view for the given task right?

Can someone tell me how exactly I should upload my code as a zip? the submission link is only allowing me to attach a document.
