punkapi | Crowd Sourcing an API from BrewDog 's hugely generous DIY Dog | REST library

I have a service class that makes an api call and stores data into its property. Then my interactor class have a method where I want to make service class api call and when data will be stored - return it. I tried myself to handle this with completion handler and dispatch group, but (I suppose I just missing something) this didn't work. I would be very appreciated if you help me to deal with this problem. Thanks in advance!

Service class:

I am consuming data from this api: https://api.punkapi.com/v2/beers/random. So I have to retrieve only few fields from this json: id, name, description and mesh_temp

I am using an API to fetch and render the data it into cards. I want to add pagination and for this I'm using the React Pagination component. I'm rendering 9 cards per page, the page number and the number of cards are determined by the API url.

I am using the React modal component by material-ui (the simple modal example). The problem is that instead of the modal for the clicked card, I'm getting the modal for the last card. I managed to "capture" the data of the clicked card in a state hook, but I'm not sure how to use that to render the correct component.

This is the Home component where the cards are rendered:

I am making a rather simple API call to (https://api.punkapi.com/v2/beers) and displaying fetched data in the component, but somehow the data is not getting displayed on the page, but when I console log it the data is displayed correctly.

I am trying to make a GET request to an API, assign the response to a variable and console.log it. Currently I get null in the console and I don't know why. when I just console.log the res.data I get the data, but for some reason the value does not get assigned to the variable allBeers, how can I save the response to that variable and use it?

Here is my code:
