linux - Alexa sample project initial authentication fails with 400 -


i'm tring complete set of alexa on raspberry pi 3 b. first run:

$> cd ~/desktop/alexa-avs-sample-app/samples $> cd companionservice && npm start

which starts companion service opens port 3000 communication amazon.

then run:

$> cd ~/desktop/alexa-avs-sample-app/samples $> cd javaclient && mvn exec:exec

and alexa starts fine. prompted visit link 

https://localhost:3000/provision/<long hash here>

which presumably runs local script authenticate amazon? redirected amazon 400 page non-descript error message:

error summary 400 bad request unknown client_id request details client_id=amzn1.application-oa2-client.< hash omitted > response_type=code redirect_uri=https://localhost:3000/authresponse scope=alexa%3aall state=< hash omitted > scope_data=< hash omitted >

i think i'm missing simple can't see it. have set amazon developers account , registered device following guide https://github.com/alexa/alexa-avs-sample-app/wiki/create-security-profile .
