title: RDS Aurora AppSync Error : 400 Bad Request
body: <p>I am fairly new to aws.</p>
  
  <p>I am trying to create a simple app using Aurora and AppSync. So far, I have been able to create aurora database, connected to it using MySQL workbench, created the tables that I need.</p>
  
  <p>I have also made the AppSync APIs. And done the resolver (connected the resolver to the RDS Aurora DB).</p>
  
  <p>Here is the problem I am facing, when I try to run queries from the AppSync Queries Tab, it gives me the following error and message:</p>
  
  <pre><code>"errorType": "400 Bad Request",
  "message": "RDSHttp:{\"message\":\"HttpEndPoint is not enabled for 
  arn:aws:rds:us***:cluster:***\"}" (I replaced some details with ***)
  </code></pre>
  
  <p>I have made my Aurora accessible to the public, and I have tried to add a few incoming rules to the security group (i.e. allow all).</p>
  
  <p>However, this error still persists. I have spent a few days on it and will appreciate any help I can get to resolve this.</p>
  
  <p>Thanks in advance</p>
