Deployment issue with database resource; Deployment script not resilient to failure

When attempting to execute the deployment script, the following logs appear

Deploying Sample application.. (this might take a few minutes)

Setting connection string to cosmos db

After which, the script continues to try to deploy, even after there was a failure with the resource deployment

Additional note: Retrying with the same information fails due to the web resource already existing. The only recourse I've found is deleting the existing resource group and/or using a different unique name for the web app.

I was eventually able to deploy when targeting a different Azure location (eastus2)
