Error in "Computing differential signature tests..." step

[JunyanKan]

While running sc.metabolism.Seurat function, I encountered an error in "Computing differential signature tests..." step.
It mentioned that Error in [<-.data.frame(*tmp*, , 2, value = 0) :

The input data was a standard Seurat object and parameters were set by default.

同遇到过，后面通过更换vision的版本解决的

H got the same error, Which VERSION of vision did you use?

[460350]

I had the same error. I solved it by updating VISION to 3.0.1 with the suggestions in #17 using devtools::install_github("YosefLab/VISION"). However, it seems against what is recommended in README.md.
