problem with "minion_opts" option

[djooberlee]

here is the resource

resource "salt_host" "roster" {

...

   minion_opts = {
     grains = jsonencode({
       example_grain = "value",
       another_grain = "another value"
     })
   }
}

in the terraform.tfstate file it looks like this

             "minion_opts": {
               "grains": "{\"another_grain\": \"another value\", \"example_grain\": \"value\"}"
             },

and in execution salt-ssh my_hostname grains.items I get an error

my_hostname:
     ----------
     _error:
         Failed to return clean data
     retcode:

         ValueError: dictionary update sequence element #0 has length 1; 2 is required
     stdout:

but if changed in the terraform.tfstate file

             "minion_opts": {
               "grains": "{\"another_grain\":\"another value\",\"example_grain\":\"value\"}"
             },

as follows

             "minion_opts": {
               "grains": {"another_grain": "another value", "example_grain":"value"}
             },

then salt-ssh my_hostname grains.items works without errors

currently i fix it with liner

terraform state pull | jq '(.resources[] | select(.name == "roster") | .instances[].attributes.minion_opts.grains) |= fromjson' > terraform.tfstate
