Accepted Answer

I see two issues here.  First, you need to use the actual thing name in the merge section of your deployment config. We  don’t support interpolation for thing name yet.

Additionally, from the component log, I see it’s trying to get the “thing_name” environment variable, which doesn’t exist. For guidance on setting environment variables, you can refer to the “Setenv” recipe section here: https://docs.aws.amazon.com/greengrass/v2/developerguide/component-recipe-reference.html#:~:text=the%20following%20information%3A-,Setenv,-(Optional)%20A%20dictionary

Cheers,

I think i understand now, it failed because the component cant run unlike in version 1

Answer

Have you looked in the logs for the component itself? That might have additional information for troubleshooting. You can post it here as well, if you still don't understand what is causing the problem.
