I get the following error -
Copy code
│ Error: Normalized JSON Unmarshal Error │  │  with module.flows.prefect_deployment.deployment, │  on ../../modules/flows/main.tf line 7, in resource "prefect_deployment" "deployment": │  7: resource "prefect_deployment" "deployment" { │  │ json string value is null

You may be missing additional deployment args. We solved it by adding 
parameters
and 
parameter_openapi_schema
. It's a bit confusing because the error doesn't specify what is null. You can set 
parameters
to an empty json object if you pass in run params elsewhere.

Copy code
"prefect_flow" "flow" {
  name         = "cowsay-flow"
  workspace_id = var.prefect_cloud_workspace_id
  tags         = ["tf-test"]
}
#
resource "prefect_deployment" "deployment" {
  name                     = "Cowsay Example Deployment"
  description              = "string"
  workspace_id             = var.prefect_cloud_workspace_id
  flow_id                  = prefect_flow.flow.id
  entrypoint               = "cowsay_example.py:cowsay_flow"
  tags                     = ["staging"]
  enforce_parameter_schema = false
  parameters = jsonencode({
    "creature" : "cow",
    "message"  :"Hello World!"
  })
  parameter_openapi_schema = jsonencode({
    "type" : "object",
    "properties" : {
      "creature" :  {"type": "string"}
      "message" : {"type": "string"}
    }
  })
  paused              = false
  storage_document_id = "eb5bbb9b-b499-4895-8932-8e366aa4b627"
  version             = "v1.1.1"
  work_pool_name      = "main"
  work_queue_name     = "default"
}
I see this error even after passing parameters and parameter_openapi_schema

hmm, nothing jumps out to me immediately, but I can't see your entire config. you can try running with 
TF_LOG=debug
and see if that reports anything helpful (that error message doesn't appear to be coming from our provider from what I can see in the source code). if the debug logs don't answer the question, please open an issue in our tracker and we can try to reproduce 👍

@Mitch Nielsen - This is what I see after running with TF_LOG=debug -

hmm, not seeing anything helpful from that. could you please open an issue with the relevant info and we'll try to replicate it?

ok will do - this is just an example deployment via terraform . I am trying to get atleast a sample one working via terraform
@Mitch Nielsen - Here is the issue that I have filed - https://github.com/PrefectHQ/terraform-provider-prefect/issues/289 Thanks
thank you 1
@Mitch Nielsen - thanks for looking into this issue- i was able to get the flow to be deployed after passing all the optional params as you mentioned in the PR. But as you can see in my terraform code - i refer to the github repo block via storage_document_id which i dont see in the UI in the pull section . Hence i am not able to run the flow

I’m on mobile right now but check out our Terraform docs page, under the Blocks resource. You’ll see an example where you refer to another block using the “$ref” syntax
Copy code
resource "prefect_block" "my_dbt_run_operation_block" {
  name      = "my-dbt-operations"
  type_slug = "dbt-core-operation"

  # note the "$ref" key wrapping the "block_document_id" reference
  data = jsonencode({
    "commands"        = ["dbt deps", "dbt seed", "dbt run"]
    "dbt_cli_profile" = { "$ref" : { "block_document_id" : prefect_block.my_dbt_cli_profile.id } }
  })
}
