"window" is not available during server side rendering?

Question

React

Ask for help from those who know. the situation is as follows:
I'm trying to run a build in production, using gatsbyJS. But during the build process, a file is created

public\component---src-pages-app-js-72fe661da54bfe8b1c87.js

which tries to access the global window object. Which naturally leads to an error: error "window" is not available during server side rendering. In the code itself, I don't use window.
This is what the canvas looks like inside this file.


Perhaps some kind of webpack setting is needed, I'm not strong in this. How many projects I did on Gatsby, no setup was required.
