When connecting to an OPCUA Server using an endpoint (opc.tcp://{serverIP:port}/OPCUASserver), I am getting an error that I do not know how to interpret.
I create an OPCUAClient using:
let client = OPCUAClient.create(clientOptions);
Then call connect
try {
await client.connect(connection.endpoint);
} catch (err) {
console.log('opcuaClient: connection error: ', err);
Here is the log message that gets printed to console:
opcuaClient: connection error: Error: Invalid position : buf.length=0 pos =0

I am not sure what this error means.

I keep getting an error in my express-promise-router
var wrapHandler = function (handler) {if ("function" !== typeof handler) { var type = Object.prototype.toString.call(handler); var msg = "Expected a callback function but got a " + type; throw new Error(msg); } var handleReturn = function (args) { // Find the next function from the arguments var next = args.slice(-1)[0];
`Error is as follows:-

I know there is a problem with the callback function being passed to the "express-promise-router" module. Specifically, the error message says that it expected a callback function, but instead got an object of type "Undefined". I checked the function call and ensured that the correct callback function is being passed as an argument but to no avail.

On the online JDL-studio, I create a JDL file without any errors. After importing it, I get an error "TypeError: cannot read property 'charCodeAt" of undefined". How to find out the cause?

I find that its cause is the following email pattern:
email String required minlength(6) maxlength(255) pattern(/^\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*$/) unique,
Now, a question would be what is the acceptable email pattern for JHipster.

It works in 'server only' app.
Generating entities are only for 'full apps'?
I'm attempting to use bluebird's promisify with the node-mysql package. Node version is 4.2.4
var Promise = require('bluebird');
var mysqlClient = Promise.promisifyAll(require("mysql/lib/Connection").prototype);
Promise.promisifyAll(require("mysql/lib/Pool").prototype);
var connectionOptions = ({
host: 'localhost',
user: 'root',
password: '',
database: 'my_db'
});
var firstPost = "some sql here";
var results = [];
mysqlClient.connectAsync(connectionOptions).then(function(connection){
connection.query(firstPost, function(){
console.log('i reached line 26 of a node script. a minor miracle')
});
}).catch(function(err) {
console.log(err);
});
I get the error
[TypeError: Cannot read property 'socketPath' of undefined]

Why am I getting this error and/or how could I debug it further? I tried to remote debug it but am not sure what I'm looking at when I get a few steps down the prototype chain. The Async functions do appear to be attached to the MysqlClient object.
Remore debugging reveals that the following section in node-mysql's Connection.js file is throwing the error :
if (!this._connectCalled) {
this._connectCalled = true;
// Connect either via a UNIX domain socket or a TCP socket.
this._socket = (this.config.socketPath)
? Net.createConnection(this.config.socketPath)
: Net.createConnection(this.config.port, this.config.host);
socketpath is not something you need to define when using node-mysql directly
It seems the Bluebird docs are out of date. They miss that you also need ConnectionConfig to be available and so this was missing in my code, causing the error.
I chose to abandon this problem to preserve my sanity. There is further discussion here and you may also want to check out mysql-promise
