JSONDecodeError when using eleanor.multi_sectors

[ojhall94]

Hi eleanor team!

I'm getting the following error when trying to search for data using eleanor. Weirdly, I got it this morning, then it went away for a bit, then it came back.

I'm using:

• json v. 2.0.9
• eleanor v. 2.0.5
• Astropy v. 5.1
• Python v. 3.10.4

The code is:

ra = 20.457083
dec = -42.022861
coords = SkyCoord(ra =ra, dec =j.dec, unit = (u.deg, u.deg))
star = eleanor.multi_sectors(coords = coords, sectors = 'all',
                                tc = True, tesscut_size=50)

And the error is:

     80 """ Download Eleanor data.
     81 Data may not always be available due to not being observed by TESS, or
