Error with databricks_storage_credential resource

[JustLeo]

Hello all, I having an issue which after trying different things, still not able to find the root cause of the problem.
I have my Teraform databrick provider configure like this:

Databricks provider version= v1.49.1

provider "databricks" {
host = module.databricks.databricks.workspace_url
}

and then my "databricks_storage_credential" resource looks like this:

resource "databricks_storage_credential" "external" {
    name = azurerm_databricks_access_connector.unity.name
    azure_managed_identity {
        access_connector_id = azurerm_databricks_access_connector.unity.id
     }
   isolation_mode = "ISOLATION_MODE_ISOLATED"
   comment = "Managed by TF"
}

I have no problem with provisioning or destruction. I can even deploy later a cluster within Databricks workspace, but on certain updates, like tag update or adding a new RG, I'm getting below error:

Error: cannot read storage credential: failed during request visitor: default auth: cannot configure default credentials, please check https://docs.databricks.com/en/dev-tools/auth.html#databricks-client-unified-authentication to configure credentials for your preferred authentication method. Config: azure_client_secret=***, azure_client_id=<CLIENT_ID>, azure_tenant_id=<TENANT_ID>. Env: ARM_CLIENT_SECRET, ARM_CLIENT_ID, ARM_TENANT_ID

│ on modules/terraform-azurerm-databricks-workspace/main.tf line 191, in resource "databricks_storage_credential" "external":
│ 191: resource "databricks_storage_credential" "external" {

Looks to me that I'm missing some read permission somewhere. Any advise? Any help will be more than welcome 🙂
Thanks in advance...

Solution to this issue:
Instead of configuring the provider like this:

provider "databricks" {
   host = module.databricks.databricks.workspace_url
}

first save the value in a local and use it in the provider, like this:
locals {
   my_url = module.databricks.databricks.workspace_url
}
provider "databricks" {
   host = local.my_url
}
