Docker container ignoring folder within directory - spring-boot

Question

I've created a docker container to run a spring boot application, that when ran on the localhots requires access to a folder containing a number files. when i built the docker image , i copied the folder with these files into the container.
As you can see the folder appears to be present but the application seems to have to trouble locating the /messaging folder
container directory
Heres the error i get:
error message
below is the docker-compose i created to connect everything together.
