It seems the issue has nothing to do with Buffalo and more with my lack of understanding of Go in general.
running go mod tidy solved the issue
This command goes through the go.mod file to resolve dependencies:
- delete the packages that are not needed
- download those needed
- update the
go.sum
I am still unsure which of those actions did the trick… but the project runs now.
ps: I’ll let the in-depth explanation/correction to the Go wizard out here.
