ERROR: 'GroupedData' object is not subscriptable? In python Databricks

Question

basket = (Removals[Removals['FLEET'] =="F"]
      .groupby('ID', 'DESCRIPTION')['REMOVAL_COUNT']
      .sum().unstack().reset_index().fillna(0)
      .set_index('ID'))

This is my code and I keep getting this error:

TypeError: 'GroupedData' object is not subscriptable --------------------------------------------------------------------------- TypeError Traceback (most recent call last) in ----> 1 basket = (Removals[Removals['FLEET'] =="F"] 2 .groupby('ID', 'DESCRIPTION')['REMOVAL_COUNT'] 3 .sum().unstack().reset_index().fillna(0) 4 .set_index('ID'))

TypeError: 'GroupedData' object is not subscriptable

Is the issue in my syntax? I can't seem to find the issue.
