  alias = "test"
  address = var.vault_address
  token = var.vault_token

  headers {
    name = "X-Vault-Wrap-TTL"
    value = "600"
  }
}

resource "vault_token" "mytoken" {
  provider = vault.test
}

Error: The terraform-provider-vault_v3.7.0_x5 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.
