mwaa-public-webserver-custom-domain - unsupported version nodejs

[choneycutt]

Are there plans to update this repo (usecases/mwaa-public-webserver-custom-domain) with a supported version?
Getting the error below when issuing the sam build

/amazon-mwaa-examples/usecases/mwaa-public-webserver-custom-domain/src/lambd
a-edge/check-auth runtime: nodejs14.x architecture: x86_64 functions: CheckAuthHandler
Building functions with nodejs14.x is no longer supported by AWS SAM CLI, please update to a newer supported runtime.
For more information please check AWS Lambda Runtime Support Policy:

Build Failed
Error: Building functions with nodejs14.x is no longer supported

Tried updating the node version in template.yaml to nodejs22.x and also tried with nodejs18.x and the build completes; however the deploy does fail at the step : CREATE_FAILED Custom::UserPoolDomainLookup
