When I make API call and store the response in useState, it shows the data while running console.log(), however when this state value is passed as an argument to another component which is supposed to take the data and mapped it to show the result, it gives me an error saying
" Cannot read properties of undefined (reading 'map')"
Can anyone help me figure out what's wrong with my code?
Edit - As Mr.Silva suggested below, I added {menFootwears &&
menFootwears.map((menFootwear)=> () )}
It no longer shows error anymore, however, it also doesn't show the
data even though the data shows as an output in console.log() in
Product.jsx whereas it shows undefined in MenShoes.jsx and WomenShoes.jsx
Here's my code for Product.jsx
import { useMediaQuery } from '#mui/material';
import { Box } from '#mui/system';
import React from 'react'
import { theme } from '../style/theme';
import MenShoes from './collections/MenShoes';
import WomenShoes from './collections/WomenShoes';
export const Products = () => {
const matchScreen = useMediaQuery(theme.breakpoints.down('md'))
const [isLoading, setIsLoading] = React.useState(true);
const [menFootwears, setMenFootwears] = React.useState([]);
const [womenFootwears, setWomenFootwears] = React.useState([]);
//Women FootWears
async function fetchWomenFootwear () {
setIsLoading(true)
await fetch('https://dummyjson.com/products/category/womens-shoes')
.then(response => response.json())
.then(response => setWomenFootwears(response.products))
setIsLoading(false);
}
//Men Footwears
async function fetchMenFootwear () {
setIsLoading(true)
await fetch('https://dummyjson.com/products/category/mens-shoes')
.then(response => response.json())
.then(response => setMenFootwears(response.products))
setIsLoading(false)
}
React.useEffect(()=> {
fetchWomenFootwear()
fetchMenFootwear()
}, [])
const handleProductCard = (id) => {
console.log('hello')
}
console.log( womenFootwears, menFootwears)
return (
<Box>
<WomenShoes data={womenFootwears} onclick={handleProductCard} loadingStatus={isLoading}/>
<MenShoes data={menFootwears} onclick={handleProductCard} loadingStatus={isLoading}/>
</Box>
)
}
Both WomenShoes and MenShoes are designed using the same code except for the API response array data.

What is the reason why I am getting the error " React has detected a change in the order of Hooks called by StudentsFilter. This will lead to bugs and errors if not fixed" I have seen this warning in 2-3 components and also tried to correct it but I don't know what I am doing wrong? Can someone help me to identify it?
You're calling the useColorModeValue conditionally (and in a loop) in the return statement. That's probably the source of the error.
You should use ESLint and the "rules of hooks" rule, it would have been highlighted directly in your editor.
I am trying to fetch data with RTK Query in next.js project and everything were fine until I had to fetch some more data from /api/exams endpoint. I have fetched almost everything from that endpoint and i know that's working fine but i still can't fetch some data from it. I'll provide screenshots of all code that's related to it. ok so here is the code where endpoints are:
Then let's continue with exams-response where i define body of endpoint:
Now I will provide code in my custom hook where i import that data from api/exams endpoint query:
And now i will show code of the actual page where i use them and where i think problem may lie also with another file which i will provide after this:

To sum up guys, I want to also fetch deadlineStart and deadlineEnd but i can't. I think problem is in last file or second to last, because maybe am not defining them properly in interface props in last code. And also i almost forgot to mention that when I try to console.log(deadlineStart) in the last code it says undefined in the browser. Edited Network Pic :
here is screenshot when i console log single exams :

It seems you have checked the activeStep wrong.
Maybe the right code must be like the following:
<React.Fragment>
{activeStep !== 0 ?getStepContent(activeStep, addressFormValues, changeAddressFormValue , paymentFormValues, changePaymentFormValue) : getStepContent(activeStep)}
Do you ever consider using Context API?
React Context API
But also you can use create a checkboxValue with useState in Checkout.js and pass setCheckBoxValue to PaymentForm in getStepContent as prop. When checkbox checked trigger setCheckBoxValue and it will trigger parent component's state (Checkbox).
