Astroquery not able to retrieve survey images

[kmhess]

This seems to have started happening out of the blue, despite no changes to the code where I get the following error when trying to retrieve a survey image with astroquery:

  File "/Users/hess/SoFiA-image-pipeline/environment/bin/sofia_image_pipeline", line 33, in <module>
    sys.exit(load_entry_point('sofia-image-pipeline==1.2.5', 'console_scripts', 'sofia_image_pipeline')())

    raise ValueError(
ValueError: Quantity truthiness is ambiguous, especially for logarithmic units and temperatures. Use explicit comparisons.

I tracked this back to:

<ipython-input-7-53c67b8fadd2> in <module>

    253         if radius is not None:
    254             size_deg = str(radius.to(u.deg).value)
--> 255         elif width and height:
    256             size_deg = "{0},{1}".format(width.to(u.deg).value,
    257                                         height.to(u.deg).value)

~/SoFiA-image-pipeline/environment/lib/python3.9/site-packages/astropy/units/quantity.py in __bool__(self)

   1336             " and temperatures. Use explicit comparisons."

ValueError: Quantity truthiness is ambiguous, especially for logarithmic units and temperatures. Use explicit comparisons.

but if I run the same command without units, it complains on the next line after the elif statement that list or int objects have no attribute 'to'.

If I run SkyView.get_images without height and width, it will return an image, but then I have no control over the size.

Upgrading to astroquery 0.4.7 appears to solve the problem. But the change in behavior still doesn't make sense...is this happening locally or on the server side?
