Hi there,

This looks like an application level issue - could you please check your build logs and try to debug from there?

This is a typescript error that is saying you are trying to use a property that isn't actually defined on that type. The 'backgroundColor' property does not exist on AccountListItemProps type. Here is typescript documentation that can help understand this more https://www.typescriptlang.org/docs/handbook/advanced-types.html#type-guards-and-differentiating-types

If you can drop the part where the error shows up or link your GitHub repo I can take a look and let you know exactly what to change
