Internal Server Exception to access Bedrock Knowledge Base

Question

I wrote a code to access the Amazon Bedrock Knowledge Base and it worked successfully but now I am having the error below. How to fix it?

**Exception occurred: An error occurred (InternalServerException) when calling the RetrieveAndGenerate operation (reached max retries: 4): Internal Server Exception**

**Code:
def askQuestion2(question):
    session = boto3.Session()
    bedrock_agent_runtime = session.client('bedrock-agent-runtime')
    request = {
        "input": {'text': question},
        "retrieveAndGenerateConfiguration": {
            "type": "KNOWLEDGE_BASE",
            "knowledgeBaseConfiguration": {
                "knowledgeBaseId": "xxxxxxxxx",
                "modelArn": "arn:aws:bedrock:us-east-1::foundation-model/anthropic.claude-v2"
            }
        },
    }
