BigQuery translation from Oracle - min & max with partition & range

Question

I am trying to translate a query from Oracle to BigQuery and coming up with an error. No matter how I try to rearrange the BigQuery version, I'm not getting the results that I expect. The values are far too large on the BigQuery version. Can someone take a look and see what might be missing?

Oracle Version

MAX(LASTWK) OVER(
                                PARTITION BY  TO_CHAR(STRT_DT, 'D'), HR, TIME_INT
                                ORDER BY
                                    TRUNC(STRT_DT)
                                RANGE BETWEEN 35 PRECEDING AND 0 PRECEDING
                            ) MAXCNT,
MIN(LASTWK) OVER(
                                PARTITION BY TO_CHAR(STRT_DT, 'D'), HR, TIME_INT
                                ORDER BY
                                    TRUNC(STRT_DT)
                                RANGE BETWEEN 35 PRECEDING AND 0 PRECEDING
                            ) MINCNT

BigQuery version that isn't working as expected:

MAX(LASTWK) OVER(
                                        PARTITION BY format_date('%d',STRT_DT), HR, cast(TIME_INT as int64)
                                        ORDER BY
                                            datetime_trunc(STRT_DT, day)
                                        RANGE BETWEEN 35 PRECEDING AND 0 PRECEDING
                                    ) MAXCNT,
MIN(LASTWK) OVER(
                                        PARTITION BY format_date('%d',STRT_DT), HR, cast(TIME_INT as int64)
                                        ORDER BY
                                            datetime_trunc(STRT_DT, day)
                                        RANGE BETWEEN 35 PRECEDING AND 0 PRECEDING
                                    ) MINCNT
