Have you had experience solving complex problems related to using Go Modules in your projects?

Yes, in projects using Go Modules, there are often tasks related to dependency management:

• Version conflicts: when different dependencies require incompatible versions of the same library.
• Proxy and module cache issues: sometimes modules do not load due to network restrictions.
• Updating modules: dependencies need to be updated carefully to avoid breaking compatibility.

To solve such tasks, I used commands like go mod tidy to clean up unused dependencies, go mod vendor to create a local directory with dependencies, and also manually edited go.mod to fix the required versions.

It is also important to monitor semantic versioning and use replace in go.mod for local debugging or temporary dependency fixes.
