Invalid status code: 1

The vignette title specified in \VignetteIndexEntry{} is different from the title in the YAML metadata. The former is "using-arrow-table", and the latter is "Using Parquet files with the arrow package". If that is intentional, you may set options(rmarkdown.html_vignette.check_title = FALSE) to suppress this check.
