| Template | Why it fails | 
| --- | --- | 
| `!{yyyy}/!{MM}/` | Ends with `/` | 
| `!{channel-id}/!{topic-name}` | No `sequence-number` or `kafka-offset` | 
| `!{sequence-number}-!{kafka-offset}` | Both present (mutually exclusive) | 
| `!{kafka-offset}` | `kafka-offset` without `partition-id` | 
| `!{sequence-number}/literal-tail` | Uniqueness token not in the last segment | 
| `!{badvar}/!{sequence-number}` | Unknown variable | 
| `foo bar/!{sequence-number}` | Space is not an allowed literal character |
