The value prefix. The value format is "value_prefix{token}"
Only applies to "in" header type. Must be empty for "in" query type.
If not empty, the header value has to match (case sensitive) this prefix.

extracted after the prefix is removed.
For example, for "Authorization: Bearer {JWT}",
value_prefix="Bearer " with a space at the end.
