Error when clicking on a link to a post when production build is redeployed

[Masse Fierro]

Steps to reproduce:

• Export a production build.
• Serve its output using serve or any other http server.
• Navigate to a page with posts links.
• Re-Export the production build.
• Click on a link to a post.
• Error occurred since the new json file has a new BUILD_ID and current page points to old one.
