Thanks for the provided details.
Would you please elaborate a bit more what does it happen when you deploy your app on AppBuilder companion app?
Does the app crash or it just does not represent the content?
Notice that the Simulator and companion app testing might differ from a real device deployment because they both have some limitations.
The ultimate testing scenario will be deployment on real device by using "Build and deploy
" command when the device is connected to the workstation and "Build in cloud" > [Platform] > App package
for a remote device deployment.
Once we have fixed your build error I recommend deploying your app on actual device by using the first option above so you can debug
it if needed.
Regarding the build error you have reported, it normally happens when invalid characters
have been used in the Application Identifier
text box so please check this requirement. I know the error doesn't say so but we are going to improve that.
Notice that if you use any wildcard provisioning you will have to replace the '*' symbol with some string.
I look forward to your reply.
