Nuxeo AI AWS Integrations Don't Work

I have the following config:
 

# Rekognition Configuration
nuxeo.enrichment.save.facets=true
nuxeo.enrichment.save.tags=true
nuxeo.enrichment.raiseEvent=true
nuxeo.ai.images.enabled=true
nuxeo.enrichment.aws.images=true
nuxeo.ai.video.enabled=true
nuxeo.enrichment.aws.video=true
nuxeo.ai.aws.rekognition.role.arn=<redacted>
nuxeo.enrichment.aws.sns.topic.arn=<redacted>
nuxeo.enrichment.aws.transcribe.enabled=true

With Nuxeo Server 2023.9 all works as expected (e.g. upload a JPG image, the image automatically gets tags). In 2023.12 and 2023.13 it does not work. There are no error messages, nothing in the logs, but the enrichment never happens. I have not yet tested 2023.10 nor 2023.11 but will try to do so.

In all cases the plugin versions are nuxeo-ai-aws-4.0.1 and nuxeo-ai-core-4.0.1.
