Error: Invalid character "<" found at the beginning of JSON data

I'm struggling with a common error - the link in my browser opens fine with JSON structure, but I keep getting an error when using weatherRequest.json(): 

Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0
.

Can someone help me figure out where the problem lies?

let fetchWeather = async () => {
    const weatherRequest = await fetch(`api.openweathermap.org/data/2.5/forecast?q=München,DE&appid=my_key`);
    const weatherStore = await weatherRequest.json();
    console.log('weatherStore', weatherStore);
}

fetchWeather();

Answer №1

I personally encountered this issue and managed to solve it using two simple fixes.

  1. Instead of using fetch, switching to axios resolved the problem (although the reason fetch didn't work remains unknown).

To resolve, simply execute -> npm install axios

Then utilize by importing -> import axios from 'axios';

  1. Adding a prefix of https:// at the beginning of the API url like so 
    https://api.openweathermap.org...
    also proved to be effective.
