            Socket IO flutter not connecting
            Asked 2022-Apr-01 at 22:50

            I am facing an issue connecting my socket io flutter client to my nodejs socket io server. I am aware of the compatibility issue between the node socket io package and the flutter socket io client package. Hence, I installed only compatible versions of dependencies on both ends.

            i.e., for flutter



            Answered 2022-Apr-01 at 22:50

            As per the socket_io client readme

            In Flutter env. not (Flutter Web env.) it only works with dart:io websocket, not with dart:html websocket or Ajax (XHR), so in this case you have to add setTransports(['websocket']) when creates the socket instance.

            Try adding an options Map when you initialize your socket.

            This is just a different way of doing the same thing from the example in

            Assuming that you have only one cookie which is your jwt, you could get it with the socket param like so :



            Socket.IO - socket.on not being ran
            Asked 2022-Mar-23 at 14:41

            I have created a custom async emitter to have a server -> client -> server method.

            However, it doesn't work as expected. It emits the event, but does not run the callback.

            With Socket.IO debugging enabled, I can see that the is logging that it is emitting the correct event.

            Function code:



            Answered 2022-Mar-21 at 15:06

            Callbacks with are different and are generally referred to as acknowledgement functions

            In order to implement callbacks, the sender would need to add the function to the last parameter of the socket.emit() call.

            Socket io Throws error : You are trying to attach to an express request handler function

   is expecting an instance returned from the app.listen method (where app is an express instance)

            At 1st piece of code , you are passing an express instance which is wrong as I mentioned above

            Can't listen to event sent from feathers server to client
            Asked 2021-Dec-17 at 07:57

            I'm building a server which uses feathers and socketio.

            I'm trying to use feathers channels mechanism to notify relevant users (connections) on relevant events.
            Users belong to groups, so upon connecting to the server, I add the connection to the appropriate channels.
            Upon publishing, inside app.publish, I'm getting the right data and see that the connection is attached to the channel, but can't figure out how to listen to it on the client.

            This is a simplified channels.js:



            Answered 2021-Dec-16 at 08:17

            Does a port need to be opened on the clients end to create the channel so the communication line is 2 ways. Perhaps javascript will have some code to open up the clients port.

            Optional arguments for higher-order functions

            I try to write a binding for

            I am having trouble with a function (next() in my example code at the bottom), that either takes no argument or a error object (Js.Exn.raiseError("ERROR!")).

            I can't find a way to define a function signature that can take both types of argument as the first value.

            I am not even sure, if what I am asking for is possible in rescript, any help to solve that problem in the proper rescript way, would be appreciated.

            Answered 2021-Nov-20 at 18:44

            It's not possible in general to have a function with a variable number of arguments, but it is possible to pass either undefined or a value, which in most cases will be equivalent.

            One way to do so is to simply use the option type. If we re-define next as



            SocketIO(app) missing required positional argument 'mode'
            Asked 2021-Nov-08 at 06:27

            I'm trying to get the simple example of Flask-SocketIO working, but I'm getting an error saying I'm missing a required positional argument 'mode', even though the documentation / official example don't show such a parameter:



            Answered 2021-Nov-07 at 07:49

            After a lot of head-scratching, I realized it was happening because I accidentally imported the wrong SocketIO with my IDE: I imported socket.SocketIO instead of flask_socketio.SocketIO. When I fixed the import statement the error went away.



            The pgAdmin 4 server could not be contacted: Fatal error
            Asked 2021-Nov-04 at 12:37

            I upgrade PostgreSQL from 13.3 to 13.4 and got a fatal error by pgAdmin 4. I found other similar question that try to fix the problem deleting the folder: "C:\Users\myusername\AppData\Roaming\pgadmin\sessions" and running pgAdmin as admin but nothing happen. Also i completely remove postgres and reinstall it, and i installed pgAdmin with his separate installation, but nothing happen again. This is the error:



            Answered 2021-Sep-11 at 18:16

            This is something that seem to have changed between pgAdmin4 5.1 and 5.7. I've seen this on a machine that had been connected to a WiFi mobile hotspot (but it could happen in other circumstances).

            It has something to do with the way the dns library is used on Windows, so this could happen to other applications that use it in the same way.

            Essentially, dns.Resolver scans the Windows registry for all network interfaces found under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\

            The WiFi mobile hotspot that machine had been connected to had set a DhcpDomain key with value ".home". The dns.Resolver found this value and split it using the dot into multiple labels, one of them being empty. That caused the exception you mention: A DNS label is empty.

            This occurred even when the WiFi network was turned off: those were the last settings that had been in use and dns.Resolver didn't check whether the interface was enabled.

            The latest version of pgAdmin seems to be an older version of dnspython (1.16.0), so I'm not sure whether this has been fixed in more recent versions. For now, there seems to be two options:

            • Delete or change the DhcpDomain subkey if you find it in on of the subkeys of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ (there might even be a way to force that value through the Control Panel).

            • Connect to a different network that doesn't set this value.
