How to parse JSON to index.html?

I can get data from GraphQL in upward..yml , but It's writing

===> Hellow ===> {{cmsPageResult > json}}

I want to print the JSON data to {{messageContent}}

veniaAppShell:
    resolver: inline
    inline:
        status:
            resolver: inline
            inline: 200
        headers:
            resolver: inline
            inline:
                content-type:
                    inline: text/html
                cache-control:
                    inline: s-maxage=60
        body:
            resolver: template
            engine: mustache
            provide:
                pageType: veniaPageType.data
                pageTypeNonce: veniaPageTypeNonce.nonce
                webpackChunks: veniaWebpackChunks.scripts
                **textHellow:
                    resolver: inline
                    inline: "Hellow"
                messageContent: 
                  resolver: inline
                  inline: '{{cmsPageResult > json}}' # ???? I want cmsPageResult to show as JSON in index.html**
            template:
                resolver: file
                file:
                    resolver: inline
                    inline: './index.html'

cmsPageResult:
  url: 
    resolver: inline
    inline: "DOMAIN/graphql"
  query:
    resolver: inline
    inline: |
      query {
        storeConfig {

          logo_height
          logo_width
          store_code
        }
      }
