prevent api from being called before state is updated - reactjs

Question

I have a list of objects. I want to make an api call once the location field of the object is changed. So for that, I have a useEffect that has id, index and location as its dependencies. I have set a null check for the location, if the location isn't empty, I want to make the api call. But the thing is, the api is being called even when the location is empty, and I end up getting a 400. How can I fix this and make the call once location isn't empty?
const [plants, setPlants] = useState([
{
name: 'Plant 1',
id: uuidv4(),
location: '',
coords: {},
country: '',
isOffshore: false,
}
]);
const [locationIDObject, setlocationIDObject] = useState({
id: plants[0].id,
index: 0
});
const handlePlantLocChange = (id, index, value) => {
setPlants(
plants.map(plant =>
plant.id === id
? {...plant, location: value}
: plant
)
)
setlocationIDObject({
id: id,
index: index
})
}
const getCoords = (id, index) => {
axios.get('http://localhost:3002/api/coords', {
params: {
locAddress: plants[index].location
}
}).then((response) => {
if(response.status === 200) {
handlePlantInfoChange(id, PlantInfo.COORD, response.data)
}
})
}
const handler = useCallback(debounce(getCoords, 5000), []);
useDeepCompareEffect(() => {
if(plants[locationIDObject.index].location !== '')
handler(locationIDObject.id, locationIDObject.index);
}, [ locationIDObject, plants[locationIDObject.index].location])
return (
<div className='plant-inps-wrapper'>
{
plants.map((item, idx) => {
return (
<div key={item.id} className="org-input-wrapper">
<input placeholder={`${item.isOffshore ? 'Offshore' : 'Plant ' + (idx+1) + ' location'}`} onChange={(e) => handlePlantLocChange(item.id, idx, e.target.value)} value={item.isOffshore ? 'Offshore' : item.location} className="org-input smaller-input"/>
</div>
)
})
}
</div>
)

Answer 1

I think your useCallback is not updating when value of your variables is changing and that is the issue:
Although the check is correct, but the call is made for older values of the variable. You should update the dependencies of your useCallback:
console.log(plants) inside getCoords might help you investigate.
Try this:
const handler = useCallback(debounce(getCoords, 5000), [plants]);

So it turns out the issue was with my debouncing function. I don't know what exactly the issue was, but everything worked as expected when I replaced the debouncing function with this:
useEffect(() => {
console.log("it changing")
const delayDebounceFn = setTimeout(() => {
getCoords(locationIDObject.id, locationIDObject.index)
}, 4000)
return () => clearTimeout(delayDebounceFn)
},[...plants.map(item => item.location), locationIDObject.id, locationIDObject.index])
