Issue converting scanpy h5ad file to h5seurat in R

[LJ-dotcom]

Hi, I'm trying to use R to work with snRNAseq data in the GTEx portal found at this link: https://www.gtexportal.org/home/downloads/adult-gtex/single_cell
The file is called GTEx_8_tissues_snRNAseq_atlas_071421.public_obs.h5ad

When I run this code in R:

library(Seurat)
library(SeuratData)
library(SeuratDisk)
Convert("/Desktop/GTEx_8_tissues_snRNAseq_atlas_071421.public_obs.h5ad", dest = "h5seurat", overwrite = TRUE)
sc <- LoadH5Seurat("/Desktop/GTEx_8_tissues_snRNAseq_atlas_071421.public_obs.h5seurat")

I get the following errors:

Warning: Unknown file type: h5ad
Warning: 'assay' not set, setting to 'RNA'
Creating h5Seurat file for version 3.1.5.9900
Adding X as data
Adding raw/X as counts

A h5seurat file is produced despite the errors, and when I ran this:
library(rhdf5)
h5ls("~/Desktop/GTEx_8_tissues_snRNAseq_atlas_071421.public_obs.h5seurat")

I got a table with the following column names: group, name, otype, dclass, and dim. The table has 57 rows.

I haven't worked with this file format before, so I am unsure if this is what I am supposed to see or if the errors are causing issues.

Has anyone worked with this specific file before, or does anyone have an idea as to why these errors are occurring?
Thank you so much for taking the time to read through this!
