would you mind sharing your metadata file? and the faith_pd qza? that will help me troubleshoot locally (and you can send these to me via DM if you do not want to post here for all the world to see )
I suspect your metadata contains some kind of special character that is not illegal in and of itself but it causing the visualizer code to blow a fuse.
Thanks @Stephanieorch! Thank you for sending along your data to help be diagnose!
You found a nice little bug
Looks like the issue is the apostrophes in your metadata. This is confusing the plotting software and hence the viz gets saved but does only an error appears in the viewer (since that’s when the plots are built).
I have raised an issue to get this solved. In the mean time, just find and replace apostrophes with any other character and everything works beautifully.
