Semantic GraphQL query complains that type is Unknown for multimedia schema type

Question

The query that was working fine, but now I am getting error "Validation error of type UnknownType: Unknown type Image @ 'page/regions/components/events/image'". I had same issue with the Button too, but after Updating Schema name back and forth, saving and republishing components. the Button ( the button inline fragment query ... on Button in the query) is working fine. For image the issue could not be resolved even after following same procedure. Please help!

  query ($namespaceId: Int!, $publicationId: Int!, $pageId: Int!) {
  page(
    namespaceId: $namespaceId
    publicationId: $publicationId
    pageId: $pageId
  ) {
    title
    url
    regions {
      name
      components {
        ... on EventGroup {
          templateName
          titleStr
          events {
            ... on Event {
              templateName
              titleStr
              schedule
              location
              detail
              note
              image {
                ... on Image {
                  variants {
                    edges {
                      node {
                        path
                        downloadUrl
                      }
                    }
                  }
                }
              }
              buttons {
                ... on Button {
                  templateName
                  label
                  linkTarget
                  externalUrl
                }
              }
            }
          }
        }
        ... on ImageLink {
          templateName

          image {
            ... on Image {
              variants {
                edges {

                  }
                }
              }
            }
          }
