Deployment Error on Digital Ocean

I am having some difficulties with Deploying Applications: 10-Troubleshooting Deployment Issues (Ultimate Docker Course). My Mongo DB and vidly_web containers are up and running, but vidly_api container is constantly restarting. I can access vidly_web in my browser, but I can’t reach the api and movies endpoints.

I have checked the logs on the vidly_api container, and found the following error:

/usr/local/bin/ exec: line 8: ./ Permission denied

I am unable to resolve the error. What could be the issue? Has anyone experienced this? How do I enable the required permissions? I will appreciate any help in resolving the issue.
