astroquery: BUG: SDSS KeyNotFoundException for query_region

Hi, I am having the same problem with: astroquery 0.4.7.d python 3.10.9 numpy 1.23.5.

Using (for example) the example in the doc, as any other call:

from astropy.coordinates import SkyCoord
from astroquery.sdss import SDSS

pos = SkyCoord('0h8m05.63s +14d50m23.3s', frame='icrs')
xid = SDSS.query_region(pos, spectro=True)


Traceback (most recent call last):

  File "/var/folders/m2/32fmbv0s3hg46rj5ccx2r5g40000gn/T/ipykernel_49747/284473386.py", line 2, in <module>
    xid = SDSS.query_region(pos, spectro=True)

  File "/Users/filippo/opt/anaconda3/envs/Py310/lib/python3.10/site-packages/astroquery/utils/class_or_instance.py", line 25, in f

    arr = np.atleast_1d(np.genfromtxt(io.BytesIO(response.content),

  File "/Users/filippo/opt/anaconda3/envs/Py310/lib/python3.10/site-packages/numpy/lib/npyio.py", line 2291, in genfromtxt
    raise ValueError(errmsg)

ValueError: Some errors were detected !

    Line #17 (got 4 columns instead of 1)
    Line #21 (got 3 columns instead of 1)
    Line #31 (got 3 columns instead of 1)

It works fine on another machine running python 3.8 and astroquery 0.4.3

Yeap, testing is all clean, so if this was all, it was more painless than I expected. I’ll have a more careful look at the coverage reports, too:

Of course it worked!

As said above, investigation is ongoing about what has changed upstream.
