Troubleshooting publishing an app, w/ private package, to Connect

I'm publishing a Shiny app to Connect. It requires inclusion of a private package, because (a) the package is served by a private repository yet (b) Connect can't access that private repository.

The process for specifying a private package seems quite straightforward. I followed what I think are all of those straightforward steps. Still, I failed. Thanks in advance for any suggestions.

  1. Some facts
    a. The private package does not need to be compiled.
    b. It imports htmlwidgets, but I've tested deployment with a separate explicit library(htmlwidgets) to no avail.
    c. We've had no other problems deploying to Connect.
    d. I've confirmed that other config changes actually yield changes in Connect (that is, Connect is reading the correct config file).

Here's what I did, and ended up with:

  1. RStudio IDE 1.2 on Win10:
    a. Installed all required packages including the private package (it's called RiskGauge). I installed the private package using devtools as follows:
> library(devtools)
>devtools::install_gitlab("xxxx/RiskGauge", auth_token = "xxxxxx", host="xxxxxxx")

b. tarred, then gzipped, the RiskGuage package and named it after the commit hash (Remote SHA in the DESCRIPTION file), in this case, dafc7d31fede0fd8f61b5469221f6effae23abbb.tar.gz

  1. RStudio Connect on RHEL 7:
    a. Added a setting to /etc/rstudio-connect.gcfg:
SourcePackageDir = /opt/R-packages

b. Created directory /opt/R-packages/, w/ a subdirectory /RiskGauge/ .
c. Saved my private package's .tar.gz file in /opt/R-packages/RiskGauge/
c. Set liberal permissions on /opt/R-packages/ (and subdirectories and files therein)
d. systemctl restart rstudio-connect

  1. Back to RStudio IDE on Win10:
    a. Attempted to publish the Shiny app to Connect.

Here's my log extract:
