When will additional file types be supported in bedrock?

As of the latest available information, Amazon Bedrock does not currently have announced plans for supporting additional file types like .css, .scss, or .html.liquid. The documentation you referenced primarily focuses on text-based document formats for use with knowledge bases and chat functionalities.

However, Amazon Bedrock is continuously evolving, and new features are regularly added. While there's no specific timeline for supporting these custom file types, Amazon has been expanding Bedrock's capabilities. For instance, they recently introduced the ability to include documents in the chat playground and while using the Conversation API.

In the meantime, you might consider some workarounds:

1. Convert your files to supported formats before ingestion.
2. Extract the relevant text content from these files and input it as plain text.
3. Use the Bedrock Data Automation feature, which allows for more flexible document processing and custom extraction logic.

If these file types are crucial for your use case, it's recommended to keep an eye on the Amazon Bedrock documentation for updates or reach out to AWS support for more specific guidance on handling these file types within your workflow.
