Details

Fix: AEA-6055 - debugging issues with post-dated updates passed on a PR branch becasue we create a new table there but failed on merge to main:

This AWS::dynamodb::Table resource is in a UPDATE_FAILED state.
Resource handler returned message: "Cannot update GSI's properties other than Provisioned Throughput and Contributor Insights Specification. You can create a new GSI with a different name." (RequestToken: dfb5cd2a-c90c-1412-45a9-b4ae52322456, HandlerErrorCode: InvalidRequest)

So this PR creates a new secondary index to be used temporarily until we can disable post-dated updates functionality. This is why the original index is left in place.

Pull request overview

This PR introduces a new DynamoDB GSI that includes the post-dated attribute in its projection, and updates the GSUL query code to use the new index to work around CloudFormation’s inability to update existing GSI projections.

Changes:

  • Add a new GSI PharmacyODSCodePrescriptionIDIndexIncPostDated (keeping the old index unchanged).
  • Update GSUL DynamoDB query code to use the new index.
  • Update GSUL unit test expectations to match the new index name.
