Claims to be using a template, but actually - not

[OnkelTem]

I use STA via its API like this:

generateApi({ input: this.specLocalPath,, templates: 'templates', })

where templates directory contains all the templates copied from templates/base and templates/base.

In interface-data-contract I added a line:

<%
throw new Error('here')
%>

Now when I run the generator, I see that the template was located:

✨   "interface data contract" template found in "/projects/project/templates"

however the added line isn't being hit. Which means that the template isn't used.

What is going on here?
