Issue with creating Service SAS for a container with ARM template

Hi,
I am trying to create Service SAS using ARM template for one of the containers with read permission and Jan 2050 as expiry. Runs successfully but I do not see any change in Portal.

Here is the arm template:
"variables": {
"storageAccountName": "test",
"containerName": "testcontainer",
"secondContainerName": "containertwo",
"serviceSasFunctionValues": {
"canonicalizedResource": "[concat('/blob/', variables('storageAccountName'), '/', variables('containerName'))]",
"signedResource": "c",
"signedPermission": "r",
"signedExpiry": "2050-01-01T00:00:00Z"
}
}

"outputs": {
"serviceSas": {
"type": "string",
"value": "[listServiceSas(variables('storageAccountName'), '2018-02-01', variables('serviceSasFunctionValues')).serviceSasToken]"
}
}

Start with the inline ARM template, especially the serviceSasFunctionValues variables and the listServiceSas output. Reproduce the deployment and compare its output with the expected Portal behavior; the issue is complete when the missing change is explained and a corrected template or documented limitation is identified.
