Debug Output/Panic Output

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

Expected Behaviour

The Azure Event Grid Topic should be deployed and both the "input_mapping_fields" and "input_mapping_default_values" objects should be set to the values defined in the resource deployment. See below:

InputMappingField : {[id, id], [topic, topic], [eventtime, time], [eventtype, event], [subject, subject], [dataversion, data]}
InputMappingDefaultValue : {[eventtype, testtype], [subject, testsubject], [dataversion, testdata]}

Actual Behaviour

The Azure Event Grid Topic resource deploys, but the "event_type", "subject", and "data_version" values for "input_mapping_fields" are missing and not set. See below:

Using Az PowersShell cmdlet to pull the fields and default values from Azure.

InputMappingField : {[id, id], [topic, topic], [eventtime, time]}
InputMappingDefaultValue : {[eventtype, testtype], [subject, testsubject], [dataversion, testdata]}
