How I sync images to amazon Kendra?

Hi,

PNG is not a format supported by Kendra.

See list of supported formats at https://docs.aws.amazon.com/kendra/latest/dg/index-document-types.html

If you need to index images, you will have to fetch them in another way and use the vision capabilities of models like Claude Sonnet to describe their content. You can then inject this content into a Bedrock Knowledge Base. Re. Claude Sonnet capabilities, see my previous article at https://repost.aws/articles/AReXoGO615SFSqDIVtcLaAGw/anthropic-claude-3-sonnet-vision-capabilities

Best,

Didier
