Bedrock Knowledge Base Failed to Fetch Error

Question

Hi, I am starting to look at Bedrock Knowledge Base but when i try to create a knowledge base i get a "Failed to create the Amazon Opensearch Serverless collection. Failed to fetch" error.

I have tried creating from S3 bucket using default SSE (with bucket key enabled) using both a small csv file and a pdf.  I have also tried using the preview webcrawler against a public website but every time the same error.  S3 bucket and Bedrock running on N. Virginia

Has anyone else experienced this and found the solution.

Hello.

Judging from the error message, creation of Opensearch Serverless used by Bedrock Knowledge Base has failed.  
There may be a problem when creating Opensearch Serverless, so please search for the event "CreateCollection" in the CloudTrail event history and check if an error has occurred.
