pandas associated KeyError: 'query_value' ?

[jpsmith5]

Hello, I was testing on a handful of samples and received the following KeyError. This error occurs in versions 2.0.0/2.0.1/2.0.2. Current pandas version is 1.2.3. Not sure if this is related to the chromosomes with no peaks or something else. Happy to provide any additional information that would be helpful.

The above exception was the direct cause of the following exception:

Thanks for reporting the issue. Seems like because no peaks were called, then the empty dataframe did not have the corresponding column. I can better guard this in the next version.
