AWS Bedrock `Internal Server Exception`

Question

We have been making extensive use of AWS Bedrock the past couple months. I've noticed that I sometimes get an `Internal Server Exception` when trying to Retrieve or retrieveAndGenerate. This happens with the AWS Console or using the user program we created.

The only way I've been able to 'fix' it, is if I delete the KnowledgeBase and make a new one. This is frustrating because it can take upwards of 2 days to sync the Knowledge Base with Titan as well as the associated cost with paying for the Knowledge Base itself and the embedding costs.

We currently have 7 KnowledgeBases and this has happened three times

Please advise.

Answer

I would recommend opening a Support Case for this to allow support to investigate logs and determine the source of the issue.
