unable remove connection based on a condition.

Hi,

I have 4 nodes in drawflow namely
this.nodes = [
{ name: 'node1' },
{ name: 'node2' },
{ name: 'node3' },
];
i am creating connection like this
this.editor.on('connectionCreated', (connection: any)

my connection object is {
"output_id": "1",
"input_id": "2",
"output_class": "output_1",
"input_class": "input_1"
}

My scenarios:

1. need to allow connection from node1 to node2 only
2. If I tried to connect to node3 i need to remove that connection

so for removing connection

const sourceNode = this.editor.drawflow.drawflow[this.editor.module].data[sourceNodeId].data.name;
const targetNode = this.editor.drawflow.drawflow[this.editor.module].data[targetNodeId].data.name;
if (sourceNode === 'node1') {
if (['node2'].includes(targetNode)) {
console.log('Allow connection');
} else {
const outputNode = this.editor.getNodeFromId(connection.output_id);
const inputNode = this.editor.getNodeFromId(connection.input_id);
this.editor.removeSingleConnection(outputNode, inputNode,connection.output_class, connection.input_class);
}
}

but connection is not getting removed showing error.

thanks in advance
