terraform apply error

[darkslategrey]

Hi,

after doing a terraform init

version           = "1.1.7"

Error: Error applying plan:

1 error(s) occurred:

* module.gce-lb-http.google_compute_backend_service.default: 1 error(s) occurred:

* google_compute_backend_service.default: Error creating backend service: googleapi: Error 400: Invalid value for field 'resource.backends[0].group': ''. Only Instance Group URLs are allowed., invalid

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.
