Adding/updating/deleting tags on an existing resource of type of Activity log alert rule fails

Question

Hi,

Adding new tags or updating existing tags on resources of type 'Activity log alert rule' fails with the error below:

Rule is null. Activity ID: 62cba7c5-64d1-42a8-ab0c-48923802f4bb. (Code: SettingIsNull)

Steps to reproduce:

1. Select a resourece group and choose alerts
2. Create an Activity log alert rule
3. After the alert rule is created try add a tag and value, or update an existing tag value or delete an existing tag/value pair to the Activity log alert rule
4. The error below occurs

However including tags during the creation of the alert rule via the tags tab seems to work properly.

Answer 1

Hi ,

This is a weird behaviour with this specific resource on azure, here you have 2 workaround options:

• Recreate the alert rule with the tags that you want (big impact)
• Export the arm template modify and redeploy

For the second option you can go to export template and copy the template and save as a json file : e.g. alert.json

Make the modification required in tags section and redeploy with :

#If you are not login yet login with
az login
# execute here from az login
az deployment group create \
    --resource-group <your resource group of alert>\
    --template-file alert.json

That arm deployment update the tag, isn't the more nice solution , but it works.

Cheers,
