[about-code]

Seems to be a duplicate of #589

[FirstVertex]

@about-code please re-open this issue.
it is not a duplicate of #589
this error is specifically about 'ElementRef' is imported from external module '@angular/core' but never used which is never mentioned on 589.

[alan-agius4]

@hughanderson4 the issue you are mentioning relates to
angular/angular#21280

[about-code]

@leftstick would you mind reopen this issue? @hughanderson4 is right in that he points onto the ''ElementRef'-message. I was probably distracted by the 'UnhandledPromiseRejectionWarning' when classifying this as a duplicate.

[sergiubologa]

Does anyone have a workaround for this issue?
