Algolia InfiniteHits showPrevious doens't work correctly


I’m using Algolia InstantSearch on mdlbeast. I’m now implementing InfiniteHits, which works well until I call the showPrevious method.

It returns bad request with “Value too small for "page" parameter, expected integer between 0 and 9223372036854775807”

And the page in payload always has a value of ‘-1’. showMore works fine and increments the page…
Help would be appreciated! thanks
