Type defined in schema.Schema not being honored/accepted after Getting from state

[asciifaceman]

I am experiencing an issue in terraform core while developing a provider. I am defining several portions of schema.Schema with their types, but receiving unexpected outputs.

Terraform Version

Terraform v0.12.8-dev

Terraform Configuration Files

Schema Code

		Type:        schema.TypeMap,
		Optional:    true,
		Description: "Concerning GZIP, level of compression, and mimetypes",
		Elem: &schema.Resource{
			Schema: map[string]*schema.Schema{
				"enabled": {
					Type:     schema.TypeBool,
					Default:  false,
					Optional: true,
				},
				"level": {
					Type:        schema.TypeInt,
					Optional:    true,
					Default:     1,
					Description: "The level of compression used for gzip",
				},
			},
		},

Implementation Code

mapContainingCompression := d.Get("compression").(map[string]interface{})
test := mapContainingCompression["enabled"].(bool)
test2 := mapContainingCompression["level"].(int)

HCL

compression = {
    enabled = true
    level = 2
}

Debug Output

Custom debug log line log.Println(spew.Sprint(stateMap))

		2019-10-23T14:02:32.108-0700 [DEBUG]
		plugin.terraform-provider-striketracker:
		2019/10/23 14:02:32
		map[
			enabled:true
			level:2
		]

Crash Output

panic: interface conversion: interface {} is string, not bool

&

panic: interface conversion: interface {} is string, not int

Expected Behavior

The bool and int should have casted as expected (and as is done properly by other similar fields in the provider's schema).

Actual Behavior

Bool and Int fields were strings

Additional Context

This same process is working fine with other schema fields, however. Dumping the data via a log shows they are what I would expect

	map[enabled:true level:2]

( https://play.golang.org/p/37UeYsyGr-W )

Additionally, I've found nulls where defaults are set in other schemas.

[asciifaceman]

I should clarify that this schema is a subschema of a TypeList

...
		Type:        schema.TypeList,
		MaxItems:    1,
		Elem: &schema.Resource{
			Schema: map[string]*schema.Schema{
				"compression": compressionSchema,
                         },
                 },
...

[asciifaceman]

		log.Println(spew.Sprint(stateMap["enabled"]))
		c.Enabled = stateMap["enabled"].(bool)

=>

2019-10-30T17:26:07.177-0700 [DEBUG] plugin.terraform-provider-striketracker: 2019/10/30 17:26:07 true
2019-10-30T17:26:07.180-0700 [DEBUG] plugin.terraform-provider-striketracker: panic: interface conversion: interface {} is string, not bool

This has no problems in other schemas

[paultyng]

TypeMap does not support non-primitive types (ie. resources) yet. Terraform core supports this but the SDK has not surfaced this ability due to some backwards compatibility constraints. Going to merge this to #62
