Hi,

I’m trying to create flat composition of a template using docker container. I’m facing issues mentioned below after restarting docker composer.

1. During first try I’m able to create a composition, But after restarting, If I commit a composition I will get an error as mentioned below:

{  
“error”: “java.lang.IllegalArgumentException: Composition missing mandatory attribute: language”,  
“status”: “Internal Server Error”  
}

1. Secondly, I’m able to retrieve a composition using compositionId which is fetched after committing a composition. But after restarting, If I try to retrieve a same composition I can see different path coming up in the link attached below:
