Using the QtTyp=P override via PYBBG bdh () function

Question

I am trying to the get the price of a bond in my Python code using PYBBG, but the code returns the yield instead of the price. The fix for this in Excel is to add "QtTyp=P' to the function call, but i am struggling to replicate the same in my Python code.

=BDH("ZP562497 Corp","last_price", "20220101","","cols=2;rows=20", "QtTyp=P")

Returns

1/3/2022    95.875
1/4/2022    95.298
1/5/2022    94.955
1/6/2022    94.229
1/7/2022    94.321
1/10/2022   93.745
1/11/2022   93.973

=BDH("ZP562497 Corp","last_price", "20220101","","cols=2;rows=20")

but without the qtTyp parameter i get:

1/3/2022    1.685
1/4/2022    1.7475
1/5/2022    1.785
1/6/2022    1.865
1/7/2022    1.855
1/10/2022   1.9188
1/11/2022   1.8938

How can i replicate the same parameter in my python code?

I tried the following:

overrides = dict(QuoteType='P')
histBondsData = bbgReader.bdh(['ZP562497 Corp'],  'PX_LAST', dt, dt, other_request_parameters=overrides) 

but i get the following exception:

Sub-element 'QuoteType' does not exist. (0x0006000d)

Can someone please help with adding the parameter to my BDP call in Python? Thanks
