aurelia - Router navigation failed, and no previous location could be restored -

it seems when aurelia encounter problem when "compiling" views cannot precisely error's stack trace error relative it's consequence (can't load view ...)

to try it, write wrong binding this, or use wrong value converter: ... repeat.for="elt in list" ...

and get, if first view:

"router navigation failed, , no previous location restored"

how real stack trace, lack of error management very, time consuming.

nb: aurelia main.js setup this:

aurelia.use    .standardconfiguration()    .developmentlogging();
