(Classic) How to resolve the "Vertex cluster: cannot read property hasOwnProperty' of null" error in the Node-RED

This error message appears when the Vertex cluster node is configured in an incorrect way. The source of the problem is in the Vertex cluster Use routing property. To make sure that the flow is sent to the Vertex cluster, this option should be disabled.

2. Uncheck the Use routing checkbox. Then, select Done.
   

   

3. Select the Deploy button in the Node-RED to send the new configuration. Now, the error message should be gone.
