Hi, guys, I am building a shiny application with Bioconductor packages. I already specified the Bioconductor repo, the app runs well locally, and I am using packrat for this project. While publishing on shiny.io, I still got an error of updating "GenomicFeatures", but Packrat showed me I already installed the latest Windows binary version 1.32.2 of GenomicFeatures. Any idea what might be wrong?
error: Building package: GenomicFeatures Unhandled Exception: Child Task 561487436 failed: Error building image: Error fetching GenomicFeatures (1.32.2) source. Error downloading package source. Please update your BioConductor packages to the latest version and try again
