Query custom page in an Infinite Query

[Tim4497]

Hey there, maybe I am super stupid right now but I do not understand how to define a custom page/range in an Infinite Query Call:

This is my query:

export const getCalendarMatrix = ( b ) =>
  b.infiniteQuery( {
    infiniteQueryOptions : {
      initialPageParam : {
        startISO : null,
        endISO   : null  
      },
      getNextPageParam : ( pageParam ) => {
        console.log( "getNextPageParam called with:", pageParam );
        return { nextPage: pageParam };
      },
      getPreviousPageParam : ( pageParam ) => {
        console.log( "getPreviousPageParam called with:", pageParam );
        return { prevPage: pageParam };
      },
    },
    query( { queryArg, pageParam } ) {
      const { viewId, resourceOffset, resourceLimit, startISO: propStartISO, endISO: propEndISO } = queryArg;
      
      const startISO = pageParam.startISO ?? propStartISO ?? addDays( new Date().toISOString().slice( 0, 10 ), -3 );
      const endISO = pageParam.endISO ?? propEndISO ?? addDays( new Date().toISOString().slice( 0, 10 ), +3 );
      
      console.log( `Calendar Matrix Query: startISO=${startISO}, endISO=${endISO}, viewId=${viewId}` );
      
      return {
        url    : "/calendar/matrix",
        params : { startISO, endISO, viewId, resourceOffset, resourceLimit }
      };
    },
    serializeQueryArgs : ( { queryArgs } ) =>
      `matrix|${queryArgs.viewId}|off:${queryArgs.resourceOffset}|lim:${queryArgs.resourceLimit}|${queryArgs.startISO}|${queryArgs.endISO}`,
  } );

now when I scroll up quite fast in my calendar I want to fetch the current page/daterange the first and then resolve the one in between my starting point and my current date range, so I build a task queue which buffers all pages I hit while scrolling up and do last in first out:

  useEffect(() => {
    if (processingRef.current) return;
    if (!queueRef.current.length) return;

    processingRef.current = true;
    const task = queueRef.current.pop();

    const pageParam = {
      startISO: task.dates[0],
      endISO: task.dates[task.dates.length - 1],
    };

    let p;
    if (task.dir === "prev") {
      p = fetchPreviousPage({ pageParam });
    } else {
      p = fetchNextPage({ pageParam });
    }

    Promise.resolve(p).finally(() => {
      processingRef.current = false;
      forceTick((v) => v + 1);
    });
  }, [
    forceTickValue,
    fetchPreviousPage,
    fetchNextPage,
    hasNextPage,
    hasPreviousPage,
  ]);

But it seems that I cant pass any custom params as pageParam is always my last fulfilled call.

Can somone help me out please?
