The error seems to be in building the documentation. There used to be a buglet in older versions of R, 
that caused some errors in processing to cause this kind of uninformative message from low level code. 
I don't remember the R version but the time frame seems consistent. 
It may well be that some \Sexpr code is spread over more than one line, which sometimes threw errors, sometimes silently ignored the lines after the first.

Maybe it's easiest just to require R >= "more recent version.

More granularly, one of these five workflow spawns nine builds of which the ones with older R version (3.3, 3.4, 3.5) fail as seen eg for run #3:

Maybe you want to comment out runs for R versions that old, or debug why they fail. The error shown in R 3.5 (a version soon three years out of date you are not obliged to care for: CRAN uses only current, previous and next
release) is not something I have seen before:

  ── R CMD build ─────────────────────────────────────────────────────────────────
  * checking for file ‘.../DESCRIPTION’ ... OK
  * preparing ‘CECPfuns’:
  * checking DESCRIPTION meta-information ... OK
  Error in parse_Rd("/tmp/RtmpydYbB0/Rbuild4d3e1cce5e37/CECPfuns/man/getCSC.Rd",  : 
    Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'NULL'
  Execution halted
  Error: Error in proc$get_built_file() : Build process failed
  Calls: <Anonymous> ... build_package -> with_envvar -> force -> <Anonymous>
  Execution halted
  Error: Process completed with exit code 1.

Here proce$get_built_file points to `pkgbuild` which is part of a non-CRAN toolchain.  So this may not be caused by your package -- I can't tell. My preference is to keep it simpler: I usually get by with one workflow and generally at most two builds.
