mosquito | mosquito document management system supports flowcharts

I got a small issue with my D3.JS Visualization tool, I'm currently doing a sort of switch to change the input of CSV file. Here is the code where something is causing issues

After making my Sankey Diagram work I wanted to change some stuff in the JSON input file, I added two more values to have them displayed when I over a nodes but I run into an issue which leads me here. So, After adding these two values my diagram simply won't work again, first with the two values added it's output the same error in the title here's the code for both

following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.

I am new to mqtt and am trying to simply start a local instance with which I can test.

When executing

Bottom line up front: The Paho MQTT client sucessfully connects to my Mosquitto broker, but immediately disconnects when I try to publish a message or when it receives a message from a topic it's subscribed to. I've tried changing Mosquitto's listening port and authentication settings, and using two different versions of Paho MQTT, and I still have the same problem.

Now let's get into detail.

Intro: I'm making a dashboard for some facial recognition devices that communicate through MQTT. I set up a Mosquitto broker and I've had no problems connecting to it and communicating with the devices using the Paho MQTT client for Python (I made a kind of server to sync the device's info to a database). Now I'm making the web interface, so I added a WebSockets listener to my mosquitto.conf and wrote a script using the Paho MQTT library for Javascript to connect to it, subscribe to topic sgdrf/out, send a simple JSON message to topic sgdrf/in to get the list of online devices, and process the response of the Python server once it arrives.

Problem and attempted solutions: I ran the Django server, loaded the web page and opened the JS console to find that the MQTT client successfully connected to the broker but immediately disconnected when it tried to publish the message to topic sgdrf/in. Here's each line of console output with their explanations:

1. The message produced by the onSuccess function, which indicates that the client successfully connected to the Mosquitto broker:

   Conexión exitosa al broker MQTT.

2. In the onConnected function, I added console.log(uri) to see the URI used by the client to connect to the broker. I got:

   ws://localhost:61613/

3. After printing uri to console, I made the client subscribe to sgdrf/out and then print 'subscribed' to console:

   subscribed

4. Then I call get_online_devices(mqtt_client), a function which creates a simple JSON string and publishes it to the topic sgdrf/in. But first, it prints the strign to the console so that I can check it (just in case):

   {"operator":"GetOnlineDevices","messageId":96792535859850080000,"info":{}}

5. Then, when the publish method is actually executed, is when I get this error (captured by the onConnectionLost function):

   Pérdida de conexión con el broker MQTT: AMQJS0005E Internal error. Error Message: message is not defined, Stack trace: No Error Stack Available (código: 5)

I checked the Mosquitto log file and it only says when a new client was connected and then when it was disconnected because of a socket error (each time for every page reload). Tail of /var/log/mosquitto/mosquitto.log:

Trying to google this yields thousands of unrelated articles, such as setting or locking a specific orientation.

My question is, while the orientation for the phone is locked in say, portrait mode, but the screen is turned sideways, is there way to detect this shift and adjust widgets on the screen in response?

Something like

I have a text file called a.txt that has this elements in it:

my previous research on Google led me to this page:https://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html here I found some informations … and I startet trying. The testing setup is against a local mosquito. This works so far (it runs without errors), but if I send the PUBLISH message, I get disconnected from mosquito.

[edit] So the big Question is, what's wrong with the message.

I am running Mosquitto MQTT for TLS1.2 successfully with certificates generated from OpenSSL and using in the mosquitto configuration file. This also involves the Java Client to manually specify the CA certificate file which connects to mosquitto

I want to use the DigiCert Global Root CA which exists in my Java keystore.

The Mosquitto configuration file for this looks like the following:
