PATTERN_REPO_BRANCH "riv24" does NOT exist

[citrusoft]

Given THE article, https://catalog.workshops.aws/eks-fleet-management/en-US,
When I launch the CloudFormation stack, https://us-east-2.console.aws.amazon.com/cloudformation/home#/stacks/quickcreate?templateUrl=https://ws-assets-prod-iad-r-cmh-8d6e9c21a4dec77d.s3.us-east-2.amazonaws.com/28c283c1-1d60-43fa-a604-4e983e0e8038/fleet-workshop-team-stack-self.json&stackName=fleet-workshop&param_RepositoryRef=VAR::MANIFESTS_REF
Then the stack fails because of failed lambda function,
eks-fleet-workshop-EKSGITIAMReportBuildFunction6A1
And that function fails because of the failed initial execution of Build Project, EKSGITIAMStackDeployProject-Ys0DaU4WuR5H:
whose CloudWatch log reports...

  The string "riv24" appears throughout code and URLs. What string should I replace string, "riv24", with?

There are files in the repo that are hardcoded to pull from a branch named riv24 that no longer exists, and needs to be updated to a branch that exists.

Sorry I missed the initial issue. I think it should point to mainline now, the cfn may not have been updated
