Trouble with RapidAPI and React App on Netlify after Vite build

Other Questions RapidAPI

I’ve hit a snag with my React project using Vite and RapidAPI after deploying to Netlify. Everything worked great locally, but now I’m getting a weird error saying e.slice is not a function.

When I checked the network tab, I saw the RapidAPI response had a 403 code. It said I wasn’t subscribed to the API, which is odd because it worked fine before.

Here’s a simplified version of my API setup:

const apiConfig = {
  method: 'GET',
  headers: {
    'API-Key': process.env.MY_API_KEY,
    'API-Host': 'example-api.com'
  }
};

async function getData(endpoint) {
  const res = await fetch(endpoint, apiConfig);
  return res.json();
}

Any ideas why this might be failing on Netlify but not locally? I’m stumped and could use some help figuring out what’s going wrong with the deployment.

I ran into this exact problem a few months ago. It’s frustrating, but there’s a simple fix. The issue is likely with how Vite handles environment variables during the build process. By default, Vite only includes variables prefixed with VITE_ in the production build.

Try changing your environment variable name to VITE_MY_API_KEY in both your local .env file and in your code. Then, make sure to add this variable to your Netlify environment settings as well.

Also, double-check your RapidAPI subscription. Sometimes they have different tiers for development vs production use. You might need to upgrade your plan or whitelist your Netlify domain in the RapidAPI dashboard.

If you’re still stuck, try logging the API response in your deployed version to get more details on the 403 error. It could provide valuable clues about what’s going wrong.

hey, i had a similar probem. check ur .env file on netlify - make sure its there and has the right api key. also, rapidapi can be finicky with cors. try adding the netlify url to the allowed origins in ur rapidapi dashboard. if that doesnt work, mayb try using axios instead of fetch? it handles some edge cases better

I encountered a similar issue when deploying my React app to Netlify. The problem likely stems from how environment variables are handled in production. Netlify doesn’t automatically expose your local environment variables in the deployed environment. To resolve this, you need to explicitly set your API key as an environment variable in Netlify. Go to your site settings in the Netlify dashboard, navigate to the ‘Build & Deploy’ section, and add your API key under ‘Environment variables’. Make sure the variable name matches what you’re using in your code. Also, double-check that your API subscription is still active and that the key hasn’t expired. Sometimes, API providers have different rate limits or restrictions for production use versus development. If the issue persists, you might need to contact the API provider to ensure your account is configured correctly for production use.
