Project that excludes numerous taxa shows as blank page

Bug Reports
1

On the web when I show this project owned by a friend, it shows as a blank page.

https://www.inaturalist.org/projects/what-orders-are-left-for-mws-to-find

Two errors appear in the web browser console:

I found the source for the top line of the traceback, line 42 here:

https://github.com/inaturalist/inaturalist/blob/40f31e862c1202ae93f3ee9f70ae9d841786dbc9/app/webpack/projects/show/components/requirements.jsx#L36-L45

i.e. it’s trying to process one of the rules to exclude a taxon and assumes r.taxon contains a taxon. however, it is undefined so the r.taxon.id property reference fails.

The project should load now. This was the same issue as was resolved here. We suspect there’s a type of taxon merge that in rare cases is causing some old taxon IDs to go away and not get mapped properly to the latest versions. We’re working on tracking it down and fixing it

Hi, I made the bugged project. I don’t know if it will help, but I also have this list containing all the taxa excluded from the project’s filters: https://www.inaturalist.org/lists/3345862-Lifelist-of-orders
I don’t know what differences there are between how projects and lists handle taxon swaps, but maybe there’s something useful going on there? I haven’t updated the list since before the project broke
