The deployment of my Gatsby CMS is not the one I want, Google maps gatsby plugin

Question

Good evening everyone, Can someone please help me on that ?

I have my Github repo with my Gatsby CMS in it, I have two different branches, master and develop. To deploy my changes I use netlify that deploys from the master branch. Merges from my develop, I regularly deploy my master branch but it keeps on publishing like nothing happened and stays like my previous commits. Can you tell me where did I mess up with the configuration ?

Second question. I wanted to add "gatsby-source-googlemaps-static"

When I put

      resolve: `gatsby-source-googlemaps-static`,
      options: {
        key: `key`,
        center: `47.330209,-1.5219381`,
              },
          },

in my gatsby-config.js, I get this error when I try to deploy :

6:33:13 PM: error "gatsby-source-googlemaps-static" threw an error while running the sourceNodes lifecycle:
6:33:13 PM: Request failed with status code 403

Which I truly don't get. Can anybody find out with me about that too ?

Have a nice day/evening you all.
