Error message of "qiime diversity core-metrics-phylogenetic" step

I got following error message while run the “qiime diversity core-metrics-phylogenetic” step on Qiime2-2017.12 version. My last run of this step went smoothly on qiime2-2017.12. Any idea? Thanks, Gary

Hi @hotblast!

That error message means you supplied a visualization (.qzv) somewhere that was expecting to see an artifact (.qza). Without seeing the command you wrote, we can’t provide specific guidance (so if you double-check your command and are still stuck, please reply with the precise command you are running). Thanks! :t_rex:

Quick followup: we have an open issue to have a better error message displayed in this case. We’ll follow up here when the error message fix makes it into a release!

Thanks, i quickly found this mistaken after I submitted my question to forum. I wish there is a way allowing users to retract or cancel out their question before you guys spending your time on it.

QIIME 2 2018.2 is out now, and it includes a new and improved error message for this situation!
