Sequelize unable to connect to SQL Server through network - node.js

Question

My setup is the following:
I have a Virtual Machine running all of my Database processes, let's call it DB-VM.
I'm currently developing at my own workstation (completely detached from DB-VM, except that we are under the same network.
I've created a valid connection string, validated by another database connection service throughout IIS and through a Data Link Properties file (.udl) and the connection.
This connection is described by the connection string as:
Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Data Source=DB-VM\MY_DATABASE.
I tried to insert it into my Sequelize configuration as following:
const sequelize = new Sequelize({
dialect: 'mssql',
dialectModulePath: 'sequelize-msnodesqlv8',
dialectOptions: {
connectionString: 'Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Data Source=DB-VM\MY_DATABASE',
trustedConnection: true,
}
});
And then proceeded to try and authenticate through:
sequelize.authenticate().then(() => {
console.log('Connection stablished successfully!');
}).catch(err => {
console.log(err);
});
And this the error is as follows:
Notice: The database uses dynamic ports, therefore I can't specify the port through the port property.
Notice 2: The Named Pipes are disabled on my database settings, and I'm not sure if I will be able to enabled it.
Notice 3: The database is already setup to allow remote connections (it is currently used through a Webpage and works fine!

Answer 1

According to this line the sequelize-msnodesqlv8 library expects "Driver" to be a part of the connection string, otherwise it tries to guess. Besides that, all the examples of connection strings here1 and here2 are using either Server=myServerName\theInstanceName or just Server=myServerName. Instead of the Data Source=....
So step 1 is to fix you connection string. You could try one of the examples like:
dialectOptions: {
connectionString: 'Driver={SQL Server Native Client 10.0};Server=DB-VM;Database=MY_DATABASE;Trusted_Connection=yes;'
},
After that if you get a new error, please update the question.
