Issue when trying to upload shiny app

[MarcElosua]

Good morning,
First of all, thank you very much for developing such great tools!
I am aware that this is not necessarily an sctransform issue but it is worth mentioning.

When I try to upload an ShinyApp to shinyapps.io using Seurat I get the following error:
Error: Unhandled Exception: Child Task 807554307 failed: Error parsing manifest: Unable to determine package source for Bioconductor package sctransform: Repository must be specified

I am already declaring options so that bioconductor packages are within the scope of the environment via:
options(repos = BiocManager::repositories())

When trying to identify what might be going wrong I run:
rsconnect::appDependencies()
Where sctransform appears as such:
126 sctransform 0.3.1 Bioconductor

I am aware that sctransform depends on the package multtest and therefore requires biocViews.
I assume the problem here is similar to the one detailed here.

Is there a good workaround for this that can ease the deployment of shinyapps?

Again, thank you very much for your work and for your time!

Hi Marc,

I actually added the line biocViews: to the package DESCRIPTION file when I added support for the glmGamPoi package. I was hoping to get rid of a CRAN check note, but it didn't make a difference. However, I never removed that line, but it shouldn't be necessary.

Could you try to remove that line in see if that helps? I don't have experience with deploying shiny apps, so can't really give any advice.

Hi @ChristophH, Good to know biocViews is not necessary, I removed the line from the DESCRIPTION file and it worked seamlessly.
Here is a link to what I did to resolve it issue solve
