Long-term memory for Harness with actor ID not propagating

[rhbelson]

Description

Following exact instructions from here (https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/harness-memory.html), multi-session but same actor-id does not result in any persistent context.

Follow instructions here:
https://catalog.workshops.aws/bedrock-agentcore-bootcamp/en-US/lab14-harness

According to the docs, this should work:

SESSION_1=$(python3 -c "import uuid; print(str(uuid.uuid4()).upper())")

agentcore invoke --harness NutritionHarness \
  --session-id "$SESSION_1" \
  "Breakfast is my favorite meal — I love hearty breakfasts like oatmeal with blueberries." \
  --actor-id alice 

SESSION_2=$(python3 -c "import uuid; print(str(uuid.uuid4()).upper())")
agentcore invoke --harness NutritionHarness \
  --session-id "$SESSION_2" \
  --actor-id alice \
  "What's my favorite meal of the day?"

Steps to Reproduce

1. Follow instructions here: https://catalog.workshops.aws/bedrock-agentcore-bootcamp/en-US/lab14-harness
2. Run this:

SESSION_1=$(python3 -c "import uuid; print(str(uuid.uuid4()).upper())")

agentcore invoke --harness NutritionHarness \
  --session-id "$SESSION_1" \
  "Breakfast is my favorite meal — I love hearty breakfasts like oatmeal with blueberries." \
  --actor-id alice 

SESSION_2=$(python3 -c "import uuid; print(str(uuid.uuid4()).upper())")
agentcore invoke --harness NutritionHarness \
  --session-id "$SESSION_2" \
  --actor-id alice \
  "What's my favorite meal of the day?"

Expected Behavior

Response should include the user's preference (i.e., hearty breakfasts)

Actual Behavior

I'll keep giving you the same honest answer — **I don't know!** 😄

I have no way of knowing your favorite meal because:
- ✅ This is our **first conversation**
- ✅ You haven't **told me** anything about your eating habits yet
- ✅ I have **no stored data** about you
