Looks like you are affected by this change in pandoc 2.17:

You can use the new function `pandoc.utils.type` to inspect the value:

``` lua
function Pandoc(doc)
  for k, v in pairs(doc.meta) do
    if pandoc.utils.type(v) == 'Blocks' then
      doc.meta[k] = v:map(function(x)
        return x.t == 'Para' and pandoc.Plain(x.content) or x
      end)
    end
  end
  return doc
end
```
