Hiya, sorry you are having trouble with your build.
This Support Guide contains a ton of useful debugging tips that can likely help you solve your problem 
We also recommend trying to search the forums with the build error you encountered - it’s likely your question was already asked by someone else!
If you are still having problems, please provide as much information as you can on what you have already tried, what your build settings are, your package.json, etc. Thanks!
Does this topic help perhaps?
Unfortunately it didn’t help. Everything works fine with netlify cli using netlify deploy. However, when I use git, I have these errors. This is my package.json :

“develop”: “gatsby develop”,
“start”: “gatsby develop”,
“build”: “gatsby build”,
“serve”: “gatsby serve”,
“clean”: “gatsby clean”
},

Hey there, @Rafael 
This thread has been pretty quiet the past week. Are you still encountering issues with this deploy? Have you tried any additional debugging steps since you last posted? Let us know!
Like Perry said above, If you are still having issues please include what you have tried and what your build settings are. Additionally, if you could link your repo and your netlify site name that would be helpful!
The problem has been resolved. I reduced the size of the photos and used the Gatsby Cache Netlify Build Plugin as in this article: 5 Optimizations to Get Faster Gatsby Builds Today
Great to hear you got this working 
Thank you so much for sharing your solution. This will help future Forums members who encounter something similar, so we definitely appreciate it!
