I'm experiencing a NullPointerException (see the stacktrace below) resulting in a 500 status when deploying Vespa.

It seems to have appeared after I've changed a field from indexing: attribute to indexing: attribute | index. Here is a snippet of the schema:

schema product {

    document product {

        ...

        field nesteds type array<Nested> {
            struct-field foo {
-               indexing: attribute
+               indexing: attribute | index
                match: exact
            }
        }
        
        struct Nested {
            field foo type string {}
        }
    }
}

When I do vespa deploy, the process fails with a 500 HTTP status. The docker container's logs contain the following message:

We should improve the error message. Using "index" inside a struct field is currently not supported.
