💡 Hint

Common Mistakes

Using 'string' type instead of 'map(string)'

Using 'any' which is too broad for this case

The map(string) type is used to represent JSON objects with string values in Terraform.

💡 Hint

Common Mistakes

Passing the variable name as a string with quotes

Passing an undefined variable

The jsondecode() function expects a JSON string variable, so we pass var.config without quotes.

💡 Hint

Common Mistakes

Using quotes around the variable name

Using jsondecode on a string variable

The bucket name should be passed as a variable reference var.bucket_name without quotes or decoding.

4fill in blank

hard

Fill both blanks to create a JSON object variable and assign a default value.

Terraform

variable "settings" {
  type    = [1]
  default = [2]
}

Drag options to blanks, or click blank then click option'

Amap(string)

Bobject({region=string, env=string})

C{"region" = "us-east-1", "env" = "dev"}

D{region = "us-east-1", env = "dev"}

💡 Hint

Common Mistakes

Using JSON string syntax for default value

Using map(string) type without specifying keys

The variable type is an object with keys and string types, and the default value is a Terraform map with key-value pairs.

5fill in blank

hard

Complete the code to decode a JSON string and access a nested value.

Terraform

locals {
  config = jsondecode([1])
  region = config["region"]
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using dot notation for map access

Passing JSON string as a literal with quotes

We decode the JSON string variable, then access the 'region' key using square brackets.
