Issues deploying Equinix Connections

I have managed to use several terraform modules without problem. I have used the palo alto cloudgenix vm modules, palo alto firewalls modules, device link modules, and fabric cloud router module. All work okay on the lastest version of equinix/equinix. 

However as I dive into other connections I get a lot version issues. For example. 

Leveraging the cloud-router-port connection. 
https://registry.terraform.io/modules/equinix/fabric/equinix/latest/examples/cloud-router-2-port-connection

This would be used to connect the cloud router to the pa firewall mgmt interface. Documentation covers the following version. 

required_providers {

equinix = {

source = "equinix/equinix"

version = ">= 2.9.0" } } }

But code doesnt work without this version

terraform {

  required_providers {

    equinix = {

      source  = "equinix/equinix"

      version = "~> 1.26.0"

    }

  }

}

When using new versions error occurs. 

Failure. Ive redone this several times in my code base.

I can get past this error and deploy the connection with an older version but then run into version issues when attempting to leverage the virtual-device-2-eia-connection

https://registry.terraform.io/modules/equinix/fabric/equinix/latest/examples/virtual-device-2-eia-connection

here the primary problem is that on older versions. there is no resource virtual-device-connection. only fabric-device-connection. 

One thought is to completely separate the fabric cloud router to port module

Here is the original cloud router to port module
