The error message in your logs include this guidance:
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because was not found. Try installing:
* deb: libv8-dev or libnode-dev (Debian / Ubuntu)
* rpm: v8-devel (Fedora, EPEL)
* brew: v8 (OSX)
* csw: libv8_dev (Solaris)
To use a custom libv8, set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
This means that you are missing a Linux system dependency on your Connect Server. The exact dependency depends on your operating system. For example, on a Debian based system, you need to install libv8-dev.
Ask your system administrator to install the correct linux dependency for your operating system.
For example, on a Debian based system, it will be something along the lines of:
sudo apt-get install libv8-dev
