  default = jsonencode({
      bool = false

Terraform Output

No error

Behaviors

Actual Behavior

The unset default values are empty strings for all the types, including integer, date, json, etc. For the json type it encodes the JSON and netbox doesn't know how to handle it.

Expected Behavior

The default values should be represented as JSON values. In the database the column type is jsonb.

Running the following command on custom fields made by terraform vs manually shows the difference in the default values. The query I use is

select "type", "default" from extras_customfield
