...or if import of a type from upgrade_types cannot be resolved
This build error may occur in several different places, especially if switching branches or pulling latest from current branch.
upgrade_types is a at the root of the monorepo that contains shared enums and interfaces used by multiple other modules within the monorepo. Sometimes this may get out of sync in local machine.
If running local docker setup, try running make setup to reinstall and copy the types folder into the backend directory.
If that's a no go, you can do it manually or run:
cd /types
npm install
cd ../backend
cp -R ../types packages/Upgrade
