No Min/Max values in BlueFuse output - CNV upload fails

[SophieS9]

We've seen a case where the BlueFuse output doesn't have the min/max score present, which has caused the CNV upload to fail at the following section of code:

variant_classification_DB/acmg_db/views/cnv_views.py

Line 572 in f486719

#Get max sizes

Only been seen once, so not a priority, but should add an if statement in to make this value optional.
