Expected Behavior (Mandatory)

Using “updateWithCypher” function with a valid new statement to update the visualization rather than replace it.

Actual Behavior (Mandatory)

When using "renderWithCypher", the visualization is replaced normally with new result, but when using “updateWithCypher”, the visualization goes blank( the cypher statement is validated to be able to get result ).

How to Reproduce the Problem

code:
    nodeClick (node) {
      this.viz._network.off('click')
      const statement ='MATCH (n)-[r]-(m) WHERE ID(n) = ' + node.nodeId + ' RETURN n, r, m'
      this.viz.renderWithCypher(statement)
    },

Simple Example

      var config = {
        container_id: 'viz', 
        server_url: 'neo4j://localhost:7687', 
        server_user: 'neo4j',
        server_password: '123456',
        labels: {
          "工序链": {
            caption: 'name',  
            font: { size: 15, color: '#606266' },
          },
          "工艺知识": {
            caption: 'name',  
            font: { size: 15, color: '#606266' },
           },
        },
        relationships: {
          "has_process": {
          },
          "next": {
          }
        },
        arrows: true,
        hierarchical: false, 
        hierarchical_sort_method: 'directed',
        encrypted: 'ENCRYPTION_OFF',
        trust: 'TRUST_ALL_CERTIFICATES',
        initial_cypher: 'MATCH (n)-[r]-(m) WHERE n.name = "粗车" RETURN n, r, m'
      }
