[Solved] “can’t instantiate template” error in Power Automate — Fredrik Engseth

Have you tried to send an email template with Power Automate and got the error message “can’t instantiate template”? Like the error in the image below. In this post, we look at how we can solve the “can’t instantiate template” error in Power Automate.

Use case behind the error “can’t instantiate template” error

The use case behind this post is to notify owners when it was 30 days until their knowledge base articles expire. And, to solve this Power Automate is a good tool for sending out these notifications. It seems like a straightforward task to do. How difficult can it be? In this case, all previous email notifications were using standard email templates in Dynamics. We wanted to continue using templates for the ease of updating the content and avoid updating content manually in the flow if the content should change. And, we wanted to add the knowledge base article as regarding the email sent to the owner to see the activities in the timeline for the users and the knowledge base article.

After some testing, we found that when trying to set regarding tables that were not in the category list when creating an email template the “can’t instantiate template” error appeared each time. As can be seen in the image below.
