Hi Omar Farooq,

Thanks for reaching out to Mcirosoft Q&A.

Could not find member 'tags' on object of type 'Subnet'. Path 'tags', line 1, position 8.

This error indicates your template has something like below:

{ "type": "Microsoft.Network/virtualNetworks/subnets", ... "tags": { "key": "value" } }

but tags is invalid for subnets. Tags can be applied only to higher-level resources like VNet or the web app, not subnets.

Try to remove or relocate the tags property from the subnet resource.

Are you trying to deploy your code to Azure web app? If yes, how are you deploying? you can refer https://learn.microsoft.com/en-us/azure/app-service/quickstart-php?tabs=cli&pivots=platform-linux to deploy your app to Azure.
