AWS Batch Job Stuck at Runnable State

Question

I’m developing an AWS architecture to generate 3D objects from taken images of an asset.

I’m following this document, so my architecture/code/test content same as this document.

Long story short system work like this:

My problem is the job is stuck in a runnable state in AWS Batch.

What I tried so far:

• I tried to increase the compute environment vCPU.
• Tried to create a new computing environment with a higher than required vCPU for the job.
• Tried to re-trigger the job.
• Tried to clone the job.

I have no other idea why the issue is happening.
