Does Flink SQL "in" operation has length limit?

Hi,

    When I am executing the following SQL in flink 1.6.1, some error throws out saying that it has a support issue, but when I reduce the number of integers in the “in” sentence, for example,

    trackId in (124427150,71648998) , Flink does not complain anything, so I wonder is there any length limit in “in” operation?

Thanks a lot.

SELECT
    trackId as id,track_title as description, count(*) as cnt
FROM
    play
WHERE
    appName='play.statistics.trace' and
    trackId in (124427150,71648998,124493327,524043,27300837,30300481,27300809,124744768,45982512,124526566,124556427,124804208,74302264,119588973,30496269,27300288,124098818,125071530,120918746,124171456,30413034,124888075,125270551,125434224,27300195,45982342,45982468,45982355,65349883,124705962,65349905,124298305,124889583,45982338,20506255,18556415,122161128,27299018,122850375,124862362,45982336,59613202,122991190,124590280,124867563,45982332,124515944,20506257,122572115,92083574)
