when I try:
const res = await fetch(apiUrl);
if (!res.ok) throw new Error(No jokes at url: ${apiUrl});
solution can't pass the tests

There is no such section anywhere anymore

All the test are passing, but when I submit the attempt I get the following error:
EasterEgg should render li element with a name
Test Failed
Failure
TypeError: Cannot read property 'contextTypes' of undefined

TypeScript translation based on existing JavaScript version.

great one

When I try to submit it it gives error expected "Bunny" and my result shows " Bunny "

in the preloaded section, there is a function called fetch() written by the kata author. call it with an url. it mimicks the behavior of the real fetch API

not a proper issue report

could anyone help?)
I've stucked with the problem
function (it) run longer that 500ms

Oh god. It was really painfully. I sat with this problem for several hours(about 4-5).
As a result, the error was that fetch(url) should ALWAYS come immediately followed by ".then()".
You can't write

  let promise = fetch(`...`);
  promise.then(...)
  return promise

But I dont know why. May be it is related with a microtasks stack? If there is anyone who knows, please tell me the topics that I could read

new FetchError(request to ${request.url} failed, reason: ${err.message}, 'system', err)

Ok. Nice exercice for Christmas. I try to write a test for errors. It should throw an error if the given joke id does not exist.

it('should throw an error', async (done) => {
  
  Test.expectError('if no joke found for given id', async () => {
    await sayJoke(url, 12101)
  })
  
  done();
});

This code doesn't work. I think, it get a promise and don't test the method.

How I can implement it ?

You have to add a 'saySetup' and 'sayPunchLine' methods to the object of your result. So that e.g. result.saySetup() returns the corrent answer.

Tests are running against a valid api endpoint (that is hidden from us).
What you have to do :

1. call the Fetch api method using parameter (apiUrl)
2. this function will return the object which has 2 properties. And these properties have function definition (logic to get the jokeounch line...)
3. real api call is hidden from us, so you have to visualize the data using data sample given to us.
