GroupBy: Number (long) and does not comply with its supposed superclass Number (integer)

Hi,

I rana into this issue where the column type changed from int to long and the GroupBy threw:

ERROR GroupBy 3:1451:0:1443 Execute failed: Runtime class of object "24" (index 4) in row "Row0" is Number (long) and does not comply with its supposed superclass Number (integer)

Though, I tried to replicate it but failed so far. I suppose the GroupBy automatically reinterpreted the input data upon reconnecting. I will try to replicate it using aa loop later today or this week.

A very old but identical post got close automatically:

Hey Mike,
