This is because you are using a sample app that expects that there is a query input passed in input and that rejects the request if it's not present. You can run your query by passing the search chain and use the build in vespa chain. Add searcChain=vespa

Did you sort this out?
Here is the reference to searchChain
Here, you can see that this app is using mychain which directs query to TextEmbeddingSearcher, which needs input as a paremeter.
