Access-Control-Allow-Origin issue

Failed to load https://api.api.ai/v1/query?v=20150910: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

Is there anyone has the same issue can help me out

I'm having a similar issue and additional warning,
Cross-Origin Read Blocking (CORB) blocked cross-origin response https://api.api.ai/v1/query?v=20150910 with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.
Any update would be appreciated.

change apiai.js
this.uri = this.apiAiClient.getApiBaseUrl() + "query?v=" + this.apiAiClient.getApiVersion();
to
this.uri = "https://cors-anywhere.herokuapp.com/" + this.apiAiClient.getApiBaseUrl() + "query?v=" + this.apiAiClient.getApiVersion();

@zyzarvin1987 does your solution works, if sure can u please mention where should i need to change it.because i didn't see the above lines in apiai.js

Thanks.

@zyzarvin1987 I've confirmed this workaround enables you to get responses from dialogFlow, but you have to send your request to a third party, including the Authorization header which contains your token. The third party then forwards the response to you.
This is a pretty big security issue, I would not recommend this as a solution.
Any further update would be appreciated.

Just as an FYI, this is a server issue on Google's side. Hopefully they will fix it ASAP.

You can install cors-anywhere as a module on a server you control if you need the proxy capabilities but don't want to send your data to a third party: (https://www.npmjs.com/package/cors-anywhere)
