🐛 Bug Report: AppwriteException: null, Connection failed (0) - Function execution -server sdk access

[mokamhawy]

👟 Reproduction steps

• I am self hosting using docker desktop win10
• I created a simple function that list users.
• I get error AppwriteException: null, Connection failed (0)

Future<dynamic> main(final context) async {
  // Why not try the Appwrite SDK?
 
  final asd = await NetworkInterface.list();
  for (var interface in asd) {
    for (var addr in interface.addresses) {
      if (addr.type == InternetAddressType.IPv4) {
        context.log('looping...');
        context
            .log('Interface: ${interface.name}, IP address: ${addr.address}');
      }
    }
  }

  final client = Client()
      .setEndpoint('http:https://localhost/v1')
      .setProject(Platform.environment['APPWRITE_PROJECT_ID'])
      .setKey(Platform.environment['APPWRITE_API_KEY'])
      .setSelfSigned(status: true);
  final users = Users(client);

I suspect the error is from setEndpoint.

my vars:
_APP_ENV=production
_APP_DOMAIN=localhost
_APP_DOMAIN_FUNCTIONS=localhost
_APP_DOMAIN_TARGET=localhost

_APP_FUNCTIONS_RUNTIMES=node-16.0,php-8.0,python-3.9,ruby-3.0,dart-3.0
_APP_EXECUTOR_SECRET=your-secret-key
_APP_EXECUTOR_HOST=http:https://appwrite-executor/v1
_APP_EXECUTOR_RUNTIME_NETWORK=runtimes
OPEN_RUNTIMES_NETWORK=runtimes
_APP_FUNCTIONS_RUNTIMES_NETWORK=runtimes

👍 Expected behavior

get users list

👎 Actual Behavior

AppwriteException: null, Connection failed (0)

@mokamhawy, thanks for raising this issue! 🙏🏼 This usually happens if something is wrong with the endpoint value. Looking at your code, it looks like you're using localhost for the endpoint. This won't work because the runtime container will try to connect to itself rather than Appwrite. One option is to use the IP of your host machine on your LAN instead of localhost.

@stnguyen90 Thank you so much. Problem solved. for those who come later.

• appwrite 1.4.5
• in dart, in function code/src

 final client = Client()
      .setEndpoint(endpoint) // local-private ip ex. http:https://192.168.10.38/v1 NOT http:https://localhost/v1
      .setProject(projectId)
      .setKey(apiKey); // this should be generated with scope of what you need to do next

api keys from: http:https://localhost/console/project-888888.../overview/keys
