Unimplemented Feature in Solidity compiler

[prince-hope1975]

Describe the error

The error occurred while trying to store a struct in a Map

To Reproduce
Here is the GitHub gist: https://gist.github.com/prince-hope1975/2b597699662c6091119b2eb941b2a6e7#file-index-rsh
The Error occurred in the API of a parallel reduce

const Blogger = API({createblog: Fun([Bytes(280)], Null),})
const defaultBlogType = Struct([
  ["blog", Array(Maybe(Bytes), MAX_BLOGS_PER_BLOGGER)],
  ["blogger", Maybe(Address)],
  ["likes", UInt],
  ["dislikes", UInt],
]);
const bloggerInfo = new Map(defaultBlogType);

    .api(
      Blogger.createblog,
      (_) => {
        check(true, "");
      },
      (_) => {
        if (isSome(bloggerInfo[this])) return 0;
        else {
          return 10000;
        }
      },
      (blob, k) => {
        k(null);
        const newBal = isSome(bloggerInfo[this]) ? 0 : 10000;

        E.created(true);
        const userBlog = extractBlog(bloggerInfo, this);
        const blogField = Struct.toObject(userBlog);
        bloggerInfo[this] = defaultBlogType.fromObject({
          blog: isNone(bloggerInfo[this])
            ? Array.set(defaultBlogEntries, 0, MByte.Some(blob))
            : Array.set(
                blogField.blog,
                fromSome(getNoneIndex(blogField.blog), 0) %
                  MAX_BLOGS_PER_BLOGGER,
                MByte.Some(blob)
              ),
          blogger: MAddr.Some(this),
          likes: 0,
          dislikes: 0,
        });
        return [blog, bal+newBal];
      }
    )

Expected behavior
It was expected to just compile with no failures
