Can you give specific steps to what you are trying to do? The build number 0 should be OK and we pulled build number 4, the one that requited libwebp.

[sdebionne]

I have indeed build 4 in my failing pipeline and libwebp is installed:

libtiff:          4.1.0-hc3755c2_4          conda-forge                 
libwebp:          1.1.0-h56121f0_1          conda-forge

So I guess I just need to clean up the cache. Sorry for the misleading report, the devil is in the build number...

[ocefpaf]

No problem. Cleaning up the cache should fix it. Please reopen if you are still experiencing this.
