Dockerized NodeJS in Fargate can't generate a working AWS pre-signed URL-CodePudding

I have a dockerized NodeJS application, and I put the image in AWS ECR. It is working well running on my local environment with docker-compose, I can generate a pre-signed PUT URL. The pre-signed URL also works, I can upload object into it. I tried to run the same ECR image with ECS Fargate, however I can't PUT the object into the generated pre-signed URL. I get an access denied error.

Edit: I suspect the issue comes from IAM Role and Permission. I build the ECS Fargate infrastructure through CloudFormation, but it seems the role is properly set-up:

ECSTaskExecutionRole:

I've assigned the S3 permission to a wrong role. I am supposed to give the S3 permission to the Task Role, not the Task Execution Role.
