Why does using 'json' type in Metafield cause an error?

[pushdaddy]

we tried to migrate from `Metafield.valueType` to Metafield.type

but when we use type="json" as per this article

https://shopify.dev/apps/metafields/types

we get error

{
  "metafields": {
    "shop": "testsite.myshopify.com",
    "settings": {"error":"json not allowed for this object"},
    "moneyFormat": "\u003cspan class=money\u003eRs. {{amount}}\u003c\/span\u003e"
  }
}

 any idea to resolve will be great

we were using Metafield->put

it works fine with 

      "type" => "json_string"

but

     "type" => "json"

does not work

Hi,

Was just checking your post, I can not see any problem with the approach you have mentioned. Since i can not see your code can't tell very specifically but it seems like you have problem with metafield definition Mutation.

If you can share your code then i would be able to tell you exact problem.
