Error with Units and DataArray/Herbie

[jp2nyy]

Hello there,
I am trying to drop the units:
diva=(mpcalc.divergence(u10m,v10m,dx=dxnam,dy=dynam))*100*(1000-sfcpnam)+omgv
but I am getting this error
DimensionalityError: Cannot convert from '1 / second' to 'dimensionless'
When I tried to separate it like this:

diva=(mpcalc.divergence(u10m,v10m,dx=dxnam,dy=dynam).magnitude) #divergence from metpy
omgsfctest=diva*100*(1000-sfcpnam)+omgv

I get this error:
AttributeError: 'DataArray' object has no attribute 'magnitude'

Any help would be great.

I realized the issue by multiplying by units.second.
