Attempting to connect AWS Fargate to ECS returning an "Operation Timed Out" error

I have a Node.js, typescript platform with Typeorm and Postgres DB. The dev and prod stacks are managed by Pulumi and we have them hosted on AWS ECS via AWS Fargate connection. The DB is AWS RDS.

I updated our libraries on my local machine and can start the platform on my machine. To mirror the CI/CD process, we have a devDockerFile that I used to run docker locally, which works as expected. But on trying to push from local to dev, I'm encountering an "Operation Timed Out" error on AWS.

The CICD pipeline is managed by Pulumi, integrated into GitHub Actions and the error from the process is as follows:
