I am running QIIME 2018.11 which I installed with conda, and I am getting the following error message after running qiime diversity alpha-rarefaction:
Plugin error from diversity: 'set' object has no attribute 'type'
When I dig further into the log, this is what the error seems to be:
Traceback (most recent call last):
File "/home/robg/miniconda3/envs/qiime2-2018.11/lib/python3.5/site-packages/q2cli/commands.py", line 274, in __call__

AttributeError: 'set' object has no attribute 'type'
I have tried to search what this error could be attributed to, but I am struggling to find a cause. I would greatly appreciate if anyone can provide guidance on how to solve this.
