Issue with stellar mocks in the 'Visualize Galaxies and Halos' tool

Hi there,

I'm having some trouble with the 'Visualize Galaxies and Halos' tool. For example, if I look at the stellar component of a galaxy e.g.

https://www.tng-project.org/data/vis/?snap_num=92&subhalo_num=650314&partType=stars
it's rendering the image perfectly fine, but if I try to specify a band e.g.

https://www.tng-project.org/data/vis/?snap_num=92&subhalo_num=650314&partType=stars&partField=stellarBandObsFrame-sdss_r
it gives the message 'Error! Probably bad inputs, please try again.'

Is something currently down? I've spent a lot of time working with the visualizer and unless I've suddenly forgotten how to use it (which is admittedly possible) these inputs should work fine. I've tried a few random other bands, both rest and observed frame, and none of them seem to be working. I also have a script that downloads these images with a few more options e.g.

wget [options] "https://www.tng-project.org/api/TNG100-1/snapshots/92/subhalos/650314/vis.hdf5?partType=stars&partField=stell
arBandObsFrame-sdss_r&size=20&sizeType=rHalfMassStars&method=sphMap&nPixels=800,800&axes=1,2"

and this is giving ERROR 500: Internal Server Error when I try to run it now.

I just noticed Raman reported this error yesterday! I'm still having the issue though...

The gas field types look like they are working for TNG50 and TNG100 but none of the stellar field types look like they are working

Thanks also for this report! Should be all fixed.
