Renaming utils to serviceutils doesn't truly resolve the issues outlined by the revive error message: avoid meaningless package names.
serviceutils is just as meaningless as utils, and tells us nothing about what kind of functions we can expect to find in the package, and only serves as a workaround to the revive check.

Instead, I suggest identifying functions from utils that have a similar purpose or operate on similar data/structs and moving those to an aptly named package.

I have updated code now. I have divided serviceutils into two packages.
