Unfortunately, yes. Current implementation of the fpump heuristic is not

specify --binarize option to tell the mip preprocessor to replace
general integers by equivalent linear combinations of binary variables.

Note that it is probably a good idea for your integer
variables to have explicit upper and lower bounds.
'Tain't a bad idea for your other variables either.
