TypeError: Cannot read properties of undefined (reading '0') in NodeJS

I have the TypeError: Cannot read properties of undefined (reading '0') with game_id: result.data[0].game_id, warning in my terminal,

What is weird is that the console.log("result ", result); shows me what I need, but below I can't access result.data[0].game_id

Code

return promise1.then((result) => {
      console.log("result ", result); <-- ALL GOOD HERE
      if (!result && !result.data && !result.data[0]) return;
      Stream.findOne({}).then((stream) => {
        if (!stream) {
          let streamInfos = new Stream({
            game_id: result.data[0].game_id, <-- ISSUE HERE

Output of the console.log("result ", result);

{"data":
[{
 "id":"45300981596",

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
