import (
    "cloud.google.com/go/cloudsqlconn"
)

// ...

go.mod

module github.com/<some>/<repo>

require (
	cloud.google.com/go/cloudsqlconn v0.5.0
)

Install as vendor

go mod vendor

Upload to Cloud Function

gcloud functions deploy <Func> \
    --quiet \
    --entry-point <Func> \

    --region us-central1 \
    --runtime go116 \
    --env-vars-file .env.production

Thanks @wk93210. We can probably just remove all these doc.go files as modules makes the import path restriction unnecessary.

To unblock your deployment, you can install the latest commit that includes a fix with this command:

go get cloud.google.com/go/cloudsqlconn@bc57877f16a61e42c603d4dc50ff4d01fc01d9d9
