I am building a flow to selectively generate a Teams tag for a group. I have, using an OData query, filtered a SharePoint list to select the members' email addresses and appended them to a variable, and inputted that variable's output to the "Create a Tag for a Team" action. It is still failing with the same message, "UserId cannot be null or whitespace" every time. I can see the outputs from the variable and can see the properly formatted email addresses, separated by a semi-colon, but it is like the action will not allow me to create a tag using Power Automate. I can create tags manually inside Teams, and I am the owner of the channel for which I am trying to create this new tag.
