Why am I getting an error when creating a json type metafield?

[wil_dev]

Hi all!

I'v a problem when I try to create a metafield of type json:

const value = {"test":"test"}
      const response = await admin.graphql(
        `#graphql
          mutation CreateAppDataMetafield($metafieldsSetInput:[MetafieldsSetInput!]!) {
            metafieldsSet(metafields: $metafieldsSetInput) {
              metafields {
              id
              namespace
              key
            }
            userErrors {
              field
              message
            }
            }
          }
        `,
        {
          variables: {
            metafieldsSetInput: {
              namespace: "block_metafields",
              key: "test",
              type: "rich_text_field",
              value: JSON.stringify(value),
              ownerId: data.get('id')
            }
          }
        }
      )
    const metafield = await response.json()
    console.log(metafield.data.metafieldsSet.userErrors)

The console:

[
20:57:06 │ remix    │   {
20:57:06 │ remix    │     field: [ 'metafields', '0', 'value' ],
20:57:06 │ remix    │     message: 'Value is not the correct format: 
failed schema "test" is not a permitted key.'
20:57:06 │ remix    │   }
20:57:06 │ remix    │ ]

 I tried with other keys, it doesn't work... where is the error?

Thanks!

If you are trying to create "a metafield of type json" then your

 type: "rich_text_field",

 should be

 type: "json",

But if it doesn't fix the error, the error message failed schema "test" is not a permitted key suggests that the key "test" may not be allowed under the schema of the metafield or that the API call doesn't have the correct permissions to set a metafield with this key. Ensure that the key is valid and permitted under your current API permissions and the metafield definitions in Shopify.
