> InvokeHTTP docs say that a default / empty "Attributes to Send" means no attributes are attempted to be sent as HTTP headers. But InvokeHTTP uses HTTPClient::matches which in turn uses regex_search internally, instead of regex_match. regex_search is subsequence match, but we need full sequence match.
> From [PROCESSORS.md|https://github.com/apache/nifi-minifi-cpp/blob/main/PROCESSORS.md#invokehttp]: Attributes to Send    Regular expression that defines which attributes to send as HTTP headers in the request. If not defined, no attributes are sent as headers.
> A workaround could be adding "^$" around the text. A proper solution is to change to use regex_match.
