Failed to find any records in S3 object

Describe the issue:
I want to ingest json documents from an S3 folder. I created a domain and a pipeline in AWS console, and configured the pipeline using the “s3 scan” blueprint. I selected “json” for codec.
The pipeline read each json file first, and then says failed to find any records. As a result, I have 0 documents ingested to the index when I check on the dashboard. Does anyone have a solution?

Configuration:
version: “2”

aws:
region: “eu-central-1”
sts_role_arn: “arn:aws:iam::XXXXX”
