An Azure service that provides an event-driven serverless compute platform.
@Rohit Kumar B Thanks for reaching out. For your first error "azure runtime is unreachable" I will suggest you to review this document to resolve the issue. In most cases either the configuration will be missing in your function app, or the storage account is unreachable/deleted. Please verify the steps document to resolve the issue.
On your second issue "System.Private.Uri: Value cannot be null. (Parameter 'uriString')." looks like there your service bus connection string is not configured correctly/missing from your function app. Please verify your local.settings.json file and validate if all the settings are configured correctly as app settings on your function app.
In case you are not able to resolve the issues then please let me know so I can connect offline to assist you.
