function app storage queue trigger is not working with vnet integration

I have a function app in linux app service plan (Standard) with VNet integration with Storage Queue trigger configured on it. Everything works fine if there are no firewall rules enabled on storage account and I see this error as soon as the firewall rules are enabled on storage account.
The function app is configured with ***WEBSITE_RUN_FROM_PACKAGE*** with URL where package is uploaded in the container.

I am using the same subnet for storage account firewall rules and function app VNet integration.
I am able to verify the package URL works fine.
What am I doing wrong here?

```
