Yes, I'm using the same tutorial. I tried it 2 weeks ago and everything working fine.
Tried it again this week and getting [object promise] in ARN. No idea why.
I've tried everything to no avail.
Super frustrating because when the bad ARN comes up you can't edit the field to fix it.

AWS Please help ASAP

The issue is that Lex is having trouble retrieving the promise for Associated ARN...To fix this, use your cloud shell to update the id...

Use this format:
aws lexv2-models update-intent \
  --bot-id  \
  --bot-version DRAFT \
  --locale-id  \
  --intent-id  \
  --intent-name  \
  --description "Updated QnA intent with Bedrock KB" \
  --parent-intent-signature "AMAZON.QnAIntent" \
  --qn-a-intent-configuration '{
    "dataSourceConfiguration": {
      "bedrockKnowledgeStoreConfiguration": {
        "bedrockKnowledgeBaseArn": "arn:aws:bedrock:::knowledge-base/"
      }
    },
    "bedrockModelConfiguration": {
      "modelArn": "arn:aws:bedrock:::foundation-model/anthropic.claude-3-haiku-20240307-v1:0"
    }
  }'

where locale-id is your language id e.g "en_US"

Are you sure you provided the correct arn of the knowledge base in lex? it seems like the arn issue. can you reverify it?

I had used the following youtube video for setup which was highly helpful, you can follow the same
