Shinyapps.io deploy fails on package install - r

Question

I'm posting this because I have not managed to get the solutions posted other places working. I'm trying to re-deploy a shiny dash, but it is failing to install a package at deploy.
It's the BioConductor error, but the package it claims to fail for is a CRAN package, and so I have no idea what to do.
MRE:
library(ggseg); library(shiny); library(tidyverse); library(plotly)
# Define UI ----
ui <- fluidPage(
# Application title
titlePanel("Demonstration of ggseg package"),
# Sidebar with a slider input for number of bins
sidebarLayout(
sidebarPanel(
radioButtons(inputId = "atlasChoice", label="Choose atlas",
choiceValues = c("dkt_3d","yeo7_3d",),
choiceNames = c("DKT", "Yeo7"),
inline = FALSE, width = NULL),
radioButtons(inputId = "positionChoice", label="Choose position",
choices = c("LCBC left","LCBC right"),
inline = FALSE, width = NULL)
),
# Show a plot of the generated distribution
mainPanel(
uiOutput("plotUI")
)
)
)
# Define server ----
server <- function(input, output) {
output$plotUI <- renderUI({
plotlyOutput("plotlyPlot")
})
output$plotlyPlot <- renderPlotly({
cc = strsplit(input$positionChoice, " ")[[1]]
ggseg3d(atlas=input$atlasChoice,
surface=cc[1],
hemisphere=cc[2]
)
})
}
# Run the application
shinyApp(ui = ui, server = server)
My repos are set as so:
getOption("repos")
BioCsoft
"https://bioconductor.org/packages/3.7/bioc"
BioCann
"https://bioconductor.org/packages/3.7/data/annotation"

"https://bioconductor.org/packages/3.7/data/experiment"
BioCworkflows
"https://bioconductor.org/packages/3.7/workflows"

And the error is as following:

I don't know if Athanasia's solved this in the end, but I had a similar problem today, so here's what worked for me, in case it's useful for someone else :)
My app uses biomaRt, which I think depends on Biobase. When I tried to deploy, I had the error:
Error: Unhandled Exception: Child Task 601909864 failed: Error parsing manifest: Unable to
determine package source for Bioconductor package Biobase: Repository must be specified
I changed my repos settings based on instructions I found here. This alone also didn't work for me.
Once I reinstalled Biomart using BiocInstaller::biocLite(), my app deployed successfully :)
