Description:

Fixes #20077

When a non-boolean response is received by the core/Http::sendHttpRequestBy() method and no redirect header is found the explode() method attempts to execute against a string instead of an array causing a fatal error.

This PR changes the default value for the header variable in this code block from string to array.
