az storage account network-rule add \
--resource-id "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-log-analytics-workspaces/providers/Microsoft.OperationalInsights/workspaces/log-analytics-workspace-001" \

--account-name storageaccountname001The following error occurs:
Bad Request({"error":{"code":"InvalidValuesForRequestParameters","message":"Values for request parameters are invalid: networkAcls.resourceAccessRules[*].resourceId. For more information, see - https://aka.ms/storagenetworkruleset"}})
The error above is also occuring when attempting to grant access from the following Resources Types:
Microsoft.Web/sites/functions
Microsoft.Logic/workflows
To Reproduce
The issue above can be re-created consistently using the following examples.
Example 1
Run the previously described command, az storage account network-rule add, using the following syntax.
az storage account network-rule add \
--resource-id "{AZURE_RESOURCE_ID}" \
--tenant-id {TENANT_ID} \
--account-name {AZURE_STORAGE_ACCOUNT_NAME}Example 2
Attempt to make a REST API call using the az rest command.
JSON Payload is stored in the variable jsonBody.
jsonBody="{
'properties': {
'networkAcls': {
'resourceAccessRules': [
{
'tenantId': '00000000-0000-0000-0000-000000000000',
'resourceId': 'subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-log-analytics-workspaces/providers/Microsoft.OperationalInsights/workspaces/log-analytics-workspace-001'
}
],
}
}
}"Run the az rest command with the PATCH method against the target Azure Storage Account.
az rest \
--method PATCH \
--uri "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-azure-storage-account/providers/Microsoft.Storage/storageAccounts/storageaccountname001?api-version=2022-09-01" \
--body "$jsonBody"Example 3
Attempt to use az resource update to update the resourceAccessRules of the Azure Storage Account.
Run the az resource update command using the following syntax.
az resource update \
--id /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-azure-storage-account/providers/Microsoft.Storage/storageAccounts/storageaccountname001 \
--add properties.networkAcls.resourceAccessRules \
"{'resourceId'='/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-log-analytics-workspaces/providers/Microsoft.OperationalInsights/workspaces/log-analytics-workspace-001','tenantId'='00000000-0000-0000-0000-000000000000'}"
Expected Behavior
Running any of the three options above should result in the Resources being added to the networkRuleSet section of the target Azure Storage Account.
"networkRuleSet": {
"bypass": "AzureServices",
"defaultAction": "Deny",
"ipRules": [],
"resourceAccessRules":
[
{
resourceId: /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg-log-analytics-workspaces/providers/Microsoft.OperationalInsights/workspaces/log-analytics-workspace-001,
tenantId: 00000000-0000-0000-0000-000000000000
}
],
"virtualNetworkRules": []
},
