Error: The terraform-provider-commercetools_v1.15.0 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

To Reproduce

Resources : commercetools_subscription ,commercetools_shipping_method , commercetools_shipping_zone_rate

Provider config :

    commercetools = {
      source  = "labd/commercetools"
      version = "1.15.0"
    }

Works in v 1.14.3, provider version downgrade fixes temporarily the issue.
Independent of Terraform version ( tested on TF 1.8.5 , 1.9.5(latest) ) ; pipelines & macos terraform plan show same issue )
Shows the same issue during a terraform plan

Expected behavior

Clean terraform apply
