  <p><code>400 (Parse error: ?      PREFIX rdf: &lt;http://www.w3.org/1999/02/22-rdf-syntax-ns??Encountered " "&lt;" "&lt; "" at line 1, column 19.??Was expecting:??</code></p>
  
  <p>This is my code in Vue js :</p>
  
  <pre><code>methods:{
  getUrl(){
    axios.get(`
    http://localhost:3030/demo/sparql?format=json&amp;query=
    PREFIX    rdf: &lt;http://www.w3.org/1999/02/22-rdf-syntax-ns#&gt;
      SELECT *   
      WHERE {
              ?s ?p ?o
      } LIMIT 10 `).then((response) =&gt;{
        this.loading = false;
        const result = response.data.results.bindings;
        this.data = result;
        console.log(result)
      })
  }
  </code></pre>
  
  <p><strong>And here is the error in Console :</strong> </p>
  
  <p><code>xhr.js?b50d:178 GET http://localhost:3030/demo/sparql?format=json&amp;query=%20%20%20%20%20%20PREFIX%20rdf:%20%3Chttp://www.w3.org/1999/02/22-rdf-syntax-ns 400 (Parse error: ?
