Cannot create ApplicationGateway

[FairW]

I'm struggling to setup a valid bicep for ApplicationGateway using bicep/modules/microsoft.network.applicationgateways .

I get this error in my devops pipeline:

"code": "InvalidRequestFormat",
"message": "System.ArgumentNullException: Value cannot be null.\r\nParameter name: groupName"

...but nothing tells what params I send to the appgw module generates the problem... I don't see anything called groupName in the template.

Also; there are no more error details in the portal - deploy target Resource Group - deployment blade:

"statusCode": "BadRequest",
        "statusMessage": "{\"error\":{\"code\":\"InvalidRequestFormat\",\"message\":\"Cannot parse the request.\",\"details\":[{\"code\":\"InvalidRequestFormat\",\"message\":\"System.ArgumentNullException: Value cannot be null.\\r\\nParameter name: groupName\"},{\"code\":\"InvalidRequestFormat\",\"message\":\"System.ArgumentNullException: Value cannot be null.\\r\\nParameter name: groupName\"}]}}",
        "eventCategory": "Administrative",

-Any tip?

Ever found out what the problem was, because I am bumping into the same problem here.

Thanks.

OK, for me the issue was that I did not use the subscription id and resource group name when using the resourceid() method in bicep. After adding these, the problem was gone.
