malformed module path "xxxx/xxxx/uuid" missing dot in first path element when migrating from GOPATH based dep to go mod

Question

$ go version
1.13.3

I have a folder structure as follows:

GOPATH
+---src
     +--- my-api-server
           +--- my-auth-server
                 +--- main.go
           +--- my-utils
                 +--- uuid
                       +--- uuid.go

my-auth-server uses my-api-server/my-utils/uuid as a depenency

Now, when I used the GOPATH based module system, this worked fine. But when using go modules, when I run go run main.go in my-auth-server it returned error:

build command-line-arguments: cannot load my-api-server/my-utils/uuid: malformed module path "my-api-server/my-utils/uuid": missing dot in first path element

Any idea how to solve this?
