"Please provide hgnc symbols to compute gene p values!" error

[bw2]

I'm trying to run the latest version of FRASER. Everything works until I get to the results(..) function. The following code

library(FRASER)
library(annotables)
library(data.table)
library(ggplot2)
library(ggpubr)
library(dplyr)
library(purrr)
library(ggrepel)
library(plotly)
library(stringr)
library(RColorBrewer)
library(ggsci)
library(ggplot2)
library(gtable)

fds = loadFraserDataSet(".")

res = results(fds, padjCutoff={padj_threshold}, zScoreCutoff=NA, deltaPsiCutoff={delta_psi_threshold})

terminates with a "Please provide hgnc symbols to compute gene p values!" error.

I'm having a hard time tracing how the results(..) function even reaches that error which AFAIK is only raised by the aberrant(..) function when aggregate is True.
