Unable to run buffalo app without using buffalo command (sqlite)

[TechplexEngineer]

Running the app with buffalo dev works but go run main.go generates errors about sqlite3 being an unsupported dialect.
I installed buffalo using this command GO111MODULE=on go get -u -v -tags sqlite github.com/gobuffalo/buffalo/buffalo

Steps to reproduce

1. mkdir buffalo-test; cd buffalo-test
2. buffalo new --db-type sqlite3 --skip-yarn test-project
3. cd test-project
4. buffalo dev #works as expected
5. go run main.go

Output of go run main.go

[POP] 2021/01/25 10:26:01 warn - unable to load connection test: unsupported dialect 'sqlite3'
[POP] 2021/01/25 10:26:01 warn - unable to load connection production: unsupported dialect 'sqlite3'

2021/01/25 10:26:01 could not find connection named development
exit status 1
