Expected Behavior

I expected no error to have happened with this configuration, given the right values to the variables.

Actual Behavior

Got this Error message
Error: azurerm_monitor_autoscale_setting.greenvmss: expected profile.0.rule.0.metric_trigger.0.time_aggregation to be one of [Average Count Maximum Minimum Total], got Last

Steps to Reproduce

1. terraform apply

References

• Supporting Documentation which mentions Last is supported as value for time_aggregation field

[IMG-PRCSNG]

Please do check this section from this repo - The schema validation check doesn't allow Last as a valid option for the time_aggregation field.

This doesn't represent the latest code from the azure msrest spec - This PR which was merged on 20 Sep 2018, has the relevant sections which support the parameter.

This has been released in version 2.16.0 of the provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading. As an example:

provider "azurerm" {
    version = "~> 2.16.0"
}
# ... other configuration ...
