Pandas SystemError: \objects\tupleobject.c:914: bad argument to internal function - pandas

Question

I am encountering below error message sporadically.

SystemError: \objects\tupleobject.c:914: bad argument to internal function
the above was called from the actual code:
1539 slice_tmp = my_orderlog.groupby(['ticker','slice']).activeOrderSize.sum().to_frame('size').reset_index()
1540 slice_tmp['unit_size'] = slice_tmp['size']/slice_tmp['ticker'].map(wt_map)
1541 logger.info(f'TRYING TO DEBUG: {slice_tmp}')
-> 1542 breakdown = slice_tmp.groupby(['ticker','slice']).unit_size.sum().unstack(level=0)
1543 logger.info(f'TRYING TO DEBUG {breakdown}')
The SystemError of bad argument of internal functions are not repeatable and very difficult (if impossible) to catch.
Note that I try to log the in-question dataframe "slice_tmp". but when i get that and run the exact same code, i.e., the "groupby(['ticker','slice']).unit_size.sum().unstack(level=0)" in jupyter notebook, the code runs no problem.
any pointer/ some similar experiences on this odd one please? FWIW i'm running Pandas 1.2.4.
