Passing in a param that doesn't exist throws an error message with duplicate wording

In this example, `test` is not a valid param, so I'd expect an error, but the message says `Bad Request` 3 times:
```
cbruno@M1P gitlab % flowpipe pipeline run chat_post_message --pipeline-arg test=123
Error: 400 Bad Request Bad Request (Bad Request: unknown parameter specified 'test')
```
