Guide for writing function in go has issues with v2 updates

What's Wrong?

The example function in https://docs.crossplane.io/v2.0/guides/write-a-composition-function-in-go/ imports the types from provider-upjet-aws:v2:

go get github.com/crossplane-contrib/provider-upjet-aws@v2.0.0

Which results in:

❯ go get github.com/crossplane-contrib/provider-upjet-aws@v2.0.0
go: github.com/crossplane-contrib/provider-upjet-aws@v2.0.0: invalid version: module contains a go.mod file, so module path must match major version ("github.com/crossplane-contrib/provider-upjet-aws/v2")

This may possibly work after:

• https://github.com/crossplane/function-sdk-go gets a v2 compatible update, tracked in Cut a release with operation function support function-sdk-go#216
• provider-upjet-aws gets a /v2 module path, tracked in [Bug]: v2 release should have major version module suffix crossplane-contrib/provider-upjet-aws#1846

But there may be further issues blocking the entire guide working smoothly. We should revisit this guide now that v2 has shipped, make sure everything works, and make any updates that are needed.

Any news on this one ? I'd like to make use of the new github.com/crossplane-contrib/provider-upjet-aws/v2 provider :)

Now that crossplane-contrib/provider-upjet-aws#1928 has been merged, it may be feasible to update this guide and have it work smoothly! 🙏

• update Go module to contain /v2 crossplane-contrib/provider-upjet-aws#1928

I've opened a PR that updates the documentation on this topic and tested it step-by-step, should work fine after it's merged :)
