Differential Expression Widget generates a blank output and error message

[IaelWM]

Describe the bug
A clear and concise description of what the bug is.
I'm trying to analyse a gene set and find which are differentially expressed between two sample sets, using the differential expression widget from the bioinformatics add-on v 4.7.1. The analysis works fine however when I try to click the "commit" button a window pops up with the message below and the data table widget with the output is blank
'''Error encountered in widget Differential Expression:

Traceback (most recent call last):
File: "D:\OrangeStat\lib\site-packages\orangewidget\gui.py", line 2009, in do_commit
commit ( )
File " D:\OrangeStat\lib\site-
packages\orangecontrib\bioinformatics\widgets\OWDifferentialExperission.py" line 1334, in commit
gene_ids = self.data.attributes [GENE_ID_ATTRIBUTES]
KeyError: 'gene_id_attribute'
'''

Expected behavior
I expected a data table with the selected genes
