title: Cypress - GraphQL response = operation not found
body: <p>I consistently receive the response of 'operation not found' when I send a GraphQL query or mutation in Cypress. Taking tips from this post <a href="https://stackoverflow.com/a/68750026/16958500">https://stackoverflow.com/a/68750026/16958500</a> I have the following in my it block (its working in Postman)</p>
  <pre><code>it('Retrieve and Store Session Token', () =&gt; {
          const query = `mutation {
              requestSMSSessionToken(phoneNumber: &quot;1666555021&quot;){
            
               cookieKey
                tokenValue
                expires
            
                  }
              }`;
                
            cy.request({
              method: 'POST',
              url: '/', 
              headers: {
              'Content-Type': 'application/json',
              }, 
              body: { query },        
          
            }).then((res)=&gt;{
              cy.log(JSON.stringify(res))
              expect(res.status).to.eq(200)
            });
  
      })
  </code></pre>
  <p>Here is my Postman Curl Code Snippet (that's working)</p>
  <pre><code>curl --location --request POST '/' \
  --header 'Content-Type: application/json' \
  --data-raw '{&quot;query&quot;:&quot;mutation {\r\n            requestSMSSessionToken(phoneNumber: \&quot;1666555021\&quot;){\r\n          \r\n             cookieKey\r\n              tokenValue\r\n              expires\r\n          \r\n                }\r\n            }&quot;,&quot;variables&quot;:{}}'
  </code></pre>
  <p>any tips to share to get this working?</p>
