+        Provide the most minimal workspace template that reproduces the bug. 
+        Try to remove any non-coder terraform blocks. 
+        Only `data "coder_parameter"` and `data "coder_workspace_tags"` 
+        with any supporting or referenced blocks are required.
+        
+        If the template is a single `main.tf`, please include the `main.tf` in the collapsible section below. 
+        If there are multiple files, either attach the files, or create a public github repository with the directory structure. 
+        Try to avoid attaching zips or tarballs.
