Hello @Erick Narvaez 

The issue with the JS is that you are passing the data as a string to the "addPaths" while it's expecting an array.

Here's how to fix it:

1. Add an additional [] to the data you have in the default value of MatrizNodosPlano:

 "[ ['Siebel', 'BUS', 'Registro Trafico[REG-TRF]'], 

          ['SAP R3', 'BUS'],

          ['APIM', 'BUS'],

          ['BUS', 'OIC'] ]"

2. Modify your JS as follows:

var paths = $parameters.MatrizNodosPlano.replace(/'/g, '"');

paths = JSON.parse(paths);

var c = new flowjs.DiGraph();

c.addPaths(paths);

3. Use the "eval()" function to execute a string as a code snippet:

eval($parameters.ConfigNodos);

The remaining part of the code can remain the same. I will attach it as an OML.

I hope this helps!

Best regards,

Abed
