Fail to add tags to network resources (application-gateway)

Environment summary

Install Method (e.g. pip, interactive script, apt-get, Docker, MSI, edge build) / CLI version (az --version) / OS version / Shell Type (e.g. bash, cmd.exe, Bash on Windows)

apt / 2.0.29 / Ubuntu 16.04 / bash

When I'm trying to add tag to application-gateway resource with following command:

az network application-gateway create <some arguments> --tags env=dev costCenter=development

I'm getting following error:

Deployment template parse failed: 'Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Microsoft.WindowsAzure.ResourceStack.Frontdoor.Data.Entities.Tags.TagsDictionary' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
Path ''.'.

JSON template snippet from the debug output:

"resources": [{
                .....
                "tags": ["env=dev", "costCenter=development"],
                .....

Thank you for the report @sshepel. We'll get a fix into the next release. As a workaround, you can create the application gateway and then use the update command to add the tags:

az network application-gateway create -g <rg> -n <name> ... --no-wait
az network application-gateway wait -g <rg> -n <name> --exists
az network application-gateway update -g <rg> -n <name> --tags <key=val> <key=val>

Thanks a lot for taking care of this @tjprescott and for workaround also ;)
