Alexa - Refresh Token

[howi42]

This is on a Pi3.
I tried to obtain a refresh token with the given script ( auth_code.sh ),
but no success, message :
Konnte keinen Dateideskriptor finden, der auf die Konsole verweist.
Something seems to be missing.
Any other way to obtain that token :
Thanks, Wolfgang

I changed the open statement to chromium-browser and the script run, but when doing the second step :
CLIENT_ID=“my id”
CLIENT_SECRET=“my secret”
CODE=“ANsSkiyHyDzMtRmEGCCp”
GRANT_TYPE=“authorization_code”
REDIRECT_URI=“https://localhost:9745/authresponse”
curl -X POST --data “grant_type=${GRANT_TYPE}&code=${CODE}&client_id=${CLIENT_ID}&client_secret=${CLIENT_SECRET}&redirect_uri=${REDIRECT_URI}” https://api.amazon.com/auth/o2/token

I get an error message :
{“error_description”:“The authorization grant type is not supported by the authorization server”,“error”:“unsupported_grant_type”}

Thanks.

Problem solved, I got it to run.

1. The problem around the grant request was a wrong code ( cut and paste error !!!).
2. Then it run, but no micro ( snowboy related ).
   A rebuild of snowboy solved it.

Now Alexa answers my questions !
The come a bit delayed, but they come.
Compred to the sample app, the response has quite a lot of delay.
Any ideas to speed it up ?
Thanks.
