[Python] Bloomberg Python Query Returning unknown ValueError

I am trying to query specific Bloomberg tickers and write them into an excel. The code itself is pretty straightforward and I have gotten it to work for all tickers except "Move Index". When querying for the this particular ticker, I am getting the exception: raise ValueError(data) ValueError: []. I blocked out the particular query code with try-except to get more information about the error, but it's still returning the same exception with no further detail.

bloomberg_merged.to_excel(writer, sheet_name='Bloomberg', startcol=0, startrow=579, header = False)


My questions are:

1. I know its a very niche question but has anyone had any success querying Move Index in Bloomberg through python?
2. How can I better understand what the actual Valueerror is?
