Error in if (tolower(source) %in% c("github", "bitbucket", "source")) { : argument is of length zero

I can run my app locally. when I try to deploy, i get

Preparing to deploy application...DONE
Uploading bundle for application: 2991569...Error in if (tolower(source) %in% c("github", "bitbucket", "source")) { : 
  argument is of length zero
Calls: <Anonymous> ... createAppManifest -> snapshotDependencies -> lapply -> FUN
In addition: Warning message:

This seems to be related to

Hello - I am running into the same issue as you. I did track it down to when the deployment runs rsconnect::appDependencies(). I did a temporary fix though where a create a DESCRIPTION file after deployment if one does not exist.

if(!file.exists(here::here('DESCRIPTION'))) {
writeLines('Package:mypackage
Title: package
Version: 0.0.0.9000
Description: What the package does (one paragraph).
License: None
Encoding: UTF-8
LazyData: true
Roxygen: list(markdown = TRUE)
RoxygenNote: 7.1.1
', con = here::here("DESCRIPTION"))
}
