terraform-provider-ec: "Value of field 'elasticsearch.version' cannot be changed" when creating new deployment

Unsure if this is a bug or a general question, as it seems rather strange that this basic functionality wouldn’t work. Apologies if there’s an obvious step I missed.

Using terraform 0.14.7 and ec provider version v0.1.0-beta, I can not create a new deployment as per the docs in https://github.com/elastic/terraform-provider-ec/blob/master/docs/resources/ec_deployment.md

When trying, i get the error message:

Error: failed creating deployment: 2 errors occurred:
        * api error: clusters.cluster_plan_change_prohibited: The requested cluster configuration change is not permitted. Value of field 'elasticsearch.version' cannot be changed to [7.9.2]. (resources.elasticsearch[0].elasticsearch.version)
        * set "request_id" to "9sa1pv9xsnqugs7qo3rd62nyz87byja4gkxebw5k8q6hm771yu938ear8di5ykfr" to recreate the deployment resources

request.log

Expected Behavior

Im expecting a deployment to be created

Current Behavior

Error: failed creating deployment: 2 errors occurred: * api error: clusters.cluster_plan_change_prohibited: The requested cluster configuration change is not permitted. Value of field ‘elasticsearch.version’ cannot be changed to [7.9.2]. (resources.elasticsearch[0].elasticsearch.version) * set “request_id” to “9sa1pv9xsnqugs7qo3rd62nyz87byja4gkxebw5k8q6hm771yu938ear8di5ykfr” to recreate the deployment resources

## Terraform definition resource “ec_deployment” “example_minimal” { name = “my_example_deployment” region = “us-east-1” version = “7.9.2” deployment_template_id = “aws-io-optimized-v2”

elasticsearch {}

kibana {}

apm {}

enterprise_search {} }

Steps to Reproduce

1. Get an API key
2. Create terraform code for provider and resource as per the docs
3. terraform apply

Context

I am trying to create a second ec deployment using terraform, we have one previous deployment in our account, that was created through the EC portal.
