Hey there, @Manasseh 
This Support Guide contains a ton of useful debugging tips that can likely help you solve your problem 
Additionally, this Support Guide houses all of our resources for debugging build and deploy issues.
If those don’t get you on the right track, sharing your .toml or package.json would both be beneficial here. Additionally, could you share a full copy of your deploy log? The screenshot above is a good start, but more information would be beneficial for us.
