Unable to play skill

[kvopencode]

Hi andrei, first and foremost thanks for wonderful medium article and code base. I have completed the below

cloud formation - steps are complete
Dropbox upload is fine
I have checked Dynamo db - all link (dropbox share links) are good
Created skill
Created lambda function & appended the trigger
Catalog - artists and songs are complete. ER_INGESTION is also succeeded
However im unable to run / test the skill.

Do you have models.json as i require it for interaction model. Also can you please share code (index.js) for the skill

Anything which you can help here ?
