Angular httpClient - not catching PHP error object

I am tasked with connecting to an old php login api which simply returns a success or error message response object.

When I connect with the correct credentials I receive the success object and when do not I receive the error. Great!

However, httpClient does not seem to be recognizing the error object. Therefore, the object is accepted as a successful response object regardless of whether it is or it isn't.

The two relevant lines of php code:

$response = array("error" => "Combinación user-pass errónea", "success" => false, "status" => 500, "message" => "Error");
echo $json_response = safe_json_encode($response);

I then added a couple more properties to the error response in the hope of it being recognized:

$response = array("error" => "Combinación user-pass errónea", "success" => false, "status" => 403, "message" => "Error");

No luck...

I have then converted the observable into a promise so as to make the process as close as possible to the code used on an AngularJS app which uses the same login api:

let httpOptions = {
  headers: new HttpHeaders(
    { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' }),
};

let params = new HttpParams({
  fromObject: { action: "login", username: credentials.username, password: credentials.password },
});

this.httpClient.post(`http://xxxxxxxxxxx/user_controller.php`, params.toString(), httpOptions).toPromise()
.then( data => console.log(data),
        err => console.log(err) );

Still no luck...

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() ...
