RTK query is htting localhost instead of baseUrl

Question

Code below. I console.log the following error via Components/Pages/Scrap.tsx.

{status: 'PARSING_ERROR', originalStatus: 200, data: '<!DOCTYPE html>\n<html lang="en">\n  <head>\n    <met…uild` or `yarn build`.\n    -->\n  </body>\n</html>\n', error: `SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON`}

some investigation revealed in the network tab of dev tools that RTK query seems to be trying to query http://localhost:3000/scrape?url=https://somewebsite.com instead of the expected endpoint of https://localhost:7125/scrape?url=https://somewebsite.com

api/scrape-api.ts

import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';
import type { scrapeModel } from '../models/scrape-model';

export const scrapeApi = createApi({
    reducerPath: 'scrapeApi',
    baseQuery: fetchBaseQuery({ baseUrl: 'https://localhost:7125/' }),
    endpoints: builder => ({
        scrapeUrl: builder.query<scrapeModel, string>({
            query: url => `scrape?url=${url}`
        })
    })
});

export const { useScrapeUrlQuery } = scrapeApi;

store/index.ts

import { configureStore } from '@reduxjs/toolkit';
import { setupListeners } from '@reduxjs/toolkit/dist/query';
import { scrapeApi } from '../api/scrape-api';
import scrapeReducer from './scrape';

export const store = configureStore({
    reducer: {
        [scrapeApi.reducerPath]: scrapeApi.reducer,
        scrape: scrapeReducer
    },
    middleware: getDefaultMiddleware => {
        return getDefaultMiddleware().concat(scrapeApi.middleware);
    }
});

setupListeners(store.dispatch);

export type RootState = ReturnType<typeof store.getState>;

Components/Pages/Scrap.tsx

import { useEffect } from 'react';
import { useScrapeUrlQuery } from '../../api/scrape-api';

const Scrape = () => {
    const { data, error, isLoading } = useScrapeUrlQuery(
        'https://somewebsite.com'
    );

    useEffect(() => {
        if (error) {
            console.log(error);
        }
    }, [data, error, isLoading]);

    return (
        <div>
            <h1>I'm the scrape page</h1>
            {isLoading && <div>Loading...</div>}
        </div>
    );
};

export default Scrape;

Hope you got it resolved already, I had the same issue (GH discussion) as you, also sending an URL to a backend.

In my case the request went to localhost:5173 (the port Vite is running the react app on).

My issue was sending the raw URL. I've added an encodeURIComponent to my URL, after this the request was sent to the specified URL in my RTK api.

How does this not answer the question? I had the same problem as OP and described my solution to it, it is reproduceable that the unescaped URL triggers this behaviour. – timhi Jun 02 '23 at 08:09

In api/scrape-api.ts change it to

scrapeUrl: builder.query<scrapeModel, string>({
query: url => `scrape?url=${encodeURIComponent(url)}`

})
