}

Expected Behavior

External location should be created within the databricks workspace

Actual Behavior

Terraform applies without any issues, however within the databricks UI, no new external location was created.

Steps to Reproduce

1. Ensure that you have an operational databricks workspace running (Premium SKU)
2. terraform apply

Terraform and provider versions

Terraform v1.8.2
on darwin_arm64

• provider registry.terraform.io/databricks/databricks v1.42.0
• provider registry.terraform.io/hashicorp/azurerm v3.102.0
• provider registry.terraform.io/hashicorp/tfe v0.54.0

Is it a regression?

Haven't attempted previous version of provider yet. Using the latest (databricks provider v1.42.0)

Additionally, when I try to manually create the external location in the UI, I get this error message:

Which I believe validates the fact that the external location is actually created, however it's not showing up in Databricks?
