lifetimeapi Error (Failed to retrieve the environment with key )

I'm using this Forge AutomaticDeployment.

and I'm facing the below lifetimeapi error.(Failed to retrieve the environment with key ・・・)


Here is the detail. 



Are you familiar with the cause on this error?

I followed Documentation, but I'm not sure where the issue is happening.


I'm wondering if I'm missing some settings  somewhere in my Lifetime. Do I have to switch something to "ON"?...


I'd appreciate it if you could give me any good ideas.


Best,

There is some overlap between this post and one of my other posts so, I've closed this question.
