Issue with p5.js

I am trying to create 2 canvas on my HTML page and on each canvas i need to draw polygons. the points(x1,y1,x2,y2,.....,xnyn) of the polygons will be fetched from the json file. However, when i am hard-coding the points in my sketch.js file then i am able to draw the polygons but when i am trying to pull it through json, i am not able to do it. Please help me with this issue, really urgent.

Also let me know if possible i will share my code so that it will be easier to resolve it. If i can have your email id, will be really helpful to communicate.
