Gulp 3.9.1 Issues with Node 10
I got everything to build after fixing #2344 and #2345 but the website did not render correctly.
There were no build errors. Finally spotted
indicating that not all the npm dependencies were being installed. Manually restoring resulted in

It turns out this is related to Dependency of Gulp 3.9.1 causes error in Node 10.
I applied the fix as suggested in the link above to resolve. This appeared to have work but did get the following

The web pages appear to be rendering correctly but I am unsure about the 15 vulnerabilities reported.
I am experiencing a similar issue with node v10.15.1. The Website does not render correctly and the Visual Studio Task Runner Explorer reports that Gulpfile.js failed to load and the following information was in the output window: Failed to run "C:\Users\Phillips' PC\source\repos\allReady\AllReadyApp\Web-App\AllReady\Gulpfile.js"... cmd.exe /c gulp --tasks-simple gulp --tasks-simple[664]: src\node_contextify.cc:633: Assertion `args[1]->IsString()' failed. 1: 00007FF6C6760EFA v8::internal::GCIdleTimeHandler::GCIdleTimeHandler+4810 2: 00007FF6C673A296 node::MakeCallback+4518 3: 00007FF6C673A34F node::MakeCallback+4703 4: 00007FF6C670D5E8 node::DecodeWrite+12952 5: 00007FF6C6F6ADD2 v8::internal::OptimizingCompileDispatcher::Unblock+60562 6: 00007FF6C6F6BF58 v8::internal::OptimizingCompileDispatcher::Unblock+65048 7: 00007FF6C6F6B28D v8::internal::OptimizingCompileDispatcher::Unblock+61773 8: 00007FF6C6F6B1AB v8::internal::OptimizingCompileDispatcher::Unblock+61547 9: 0000035C0DB5C5C1
Did some investigation of the AppVeyor build server since this error message did not appear there - see #2351. The build server is using Node 8.15.
Installing Node 8.15 solved this problem - installed https://nodejs.org/download/release/v8.15.0/node-v8.15.0-x64.msi.
In order to ensure that Node 8.15 was being used instead of the Node 10 installed with VS2017 15.9.* the path to the Node 8.15 installation needs to added under the External Web Tools options.

Did some future proofing to support Gulp 4 in PR #2352 which works in both Node 10 and Node 8.15.
Removed knockout-bootstrap - including cause the integration test to fail intermittently. This needs to be researched further.
