Node-Red crashes getting TypeError:Cannot read property of undefined at nbrowser.js 367:19 #24

Hi, I am getting Getting TypeError:Cannot read property of undefined at nbrowser.js 367:19 and it bombs out node-red completely. I have installed nbrowser with no errors, xvfb-run is installed, as is nightmare and electron. I have tested both it running on both debian stretch and redhat 7.6 and both give the same error. Using xvfb-run --listen-tcp wget https://www.google.com.au returns the index file correctly. However, running the example in nightmare returns nothing and it completely failes in the make file. So, exactly where to test next is a little elusive, can you please point me in the right direction to help this issue. Many thanks.

May want to post in nightmarejs. Are there any other errors or info running the example in nightmare. A make error tells us that you maybe missing additional dependencies needed to have nightmare functional.

Did you follow the items mentioned in https://github.com/Steveorevo/node-red-contrib-nbrowser/issues/17 ?

Yep, thanks finally tracked it down it was a multitude of container config problems and libraries (RPM's) missing, there are just so many possible issues you must have to contend with to fault find this app although once I learned how electron and nightmare work under the covers it was easier, ...great app though !!
