/api/queries CORS error while working on localhost

[andresMRoblesistemas]

Im working in localhost to test redash.
When I try it in Postman it works. The queries are created on the instance of redash

I'm creating a redash query and then when I want to send it to /api/queries I use the following method (Dart code)

Future<String> getRedashResponse() async {
        // URL de la API de Redash
        final url = Uri.http(
          'localhost:5001',
          '/api/queries',
        );
        final body = jsonEncode({
          "query": "{\n    \"collection\":\"cliente\"\n}",
          "name": "charla ${DateTime.now()}",
          "data_source_id": 1,
          "options": {"parameters": []}
        });
        final headers = {
          'Content-Type': 'application/json',
          'Authorization': 'Key fgdffddfgdfgf',
          'Access-Control-Allow-Origin': 'strict-origin-when-cross-origin'
        };

        final response = await http
            .post(url, headers: headers, body: body)
            .timeout(const Duration(minutes: 1));

        if (response.statusCode == 200) {
          final responseJson = jsonDecode(response.body);
          final jsonString = responseJson['data'][0]['respuesta'];
          return jsonString;
        } else {
          log('Request failed with status: ${response.statusCode}');
          return 'Error: ${response.statusCode}';
        }
      }

But I get the error in the image above. How do I fix that?

Which version of Redash are you using, and what process did you use to set it up? 😄

Asking because for local development purposes (ie to do Redash development) there are guides here which are known to work: https://github.com/getredash/redash/wiki

For a standalone system that you're preparing in a production like way (even just testing in a VM), then the setup.sh script here should be good too: https://github.com/getredash/setup/

I've added a nginx.conf file and the environment variables too in the compose.yaml
docker-compose.yaml.txt
nginx.conf.txt

Still having the same issue

[justinclift]

Hmmm, the error mentions 'Access-Control-Allow-Origin'. There's a Redash environment variable for that too (REDASH_CORS_ACCESS_CONTROL_ALLOW_ORIGIN), though it doesn't look to be one of the ones you've added to your docker-compose.yaml file?

[andresMRoblesistemas]

I've tried it and it says the same error (Ive deleted every image, container and all, Ive only replace the original compose.yaml for the one with all the environment variables) Im giving up, Im moving forward with Metabase instead.

[justinclift]

No worries. It would have been interesting for you to capture the full request as made by Dart and by something that does it properly (ie you mention Postman), to see what the difference is and what Dart's doing wrong.

Hopefully Metabase works for you out of the box instead. 😄
