All Q Scenarios stopped executing in production account (previously working, no changes made)

[Rodolphe_Fares]

Hello,

We are encountering a critical issue with Amazon Q in QuickSight Scenarios.

Context

• We implemented multiple scenarios in a production QuickSight account for a client

• These scenarios were working correctly and were actively used

• No changes were made to:

  • Datasets

  • SPICE ingestion

  • Topic configuration

  • Scenario logic

Issue

Recently, all scenarios in the production account started behaving incorrectly:

• Steps do not execute

• In some cases, the scenario stops before even completing Step 1

• No error messages are shown

Key Observation

• The same scenarios (or equivalent logic) work correctly in a sandbox account

• The issue affects all scenarios, not just one

What we ruled out

• SPICE capacity → sufficient

• Dataset integrity → validated

• Prompt complexity → even simple steps fail

Question

Has anyone experienced:

• All scenarios failing or not executing in a specific account?

• Account-level issues with Q Scenarios?

• Possible backend changes or regressions affecting execution?

At this point, this appears to be an account-level or service-side issue rather than a modeling problem.

Any insights would be greatly appreciated.
