Receiving payload errors when trying to connect to REST API

I am looking to call an internal REST API and pass the payload back in Mule 3.7.3. The request is only the URL and no body but I am getting payload errors like nullPayload.

How can I get this to work?

I am testing it with this public API https://apisandbox.openbankproject.com/obp/v2.0.0/banks

and the code I have mocked up is here:

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:dw="http://www.mulesoft.org/schema/mule/ee/dw" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:tracking="http://www.mulesoft.org/schema/mule/ee/tracking" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

        <logger message="#[message.payload]" level="INFO" doc:name="Logger"/>
    </flow>
</mule>

Host should not contain a URL. It should just be the host, and HTTPS protocol specified separately. Also no need to set the payload for a GET request. updated code that works:

<?xml version="1.0" encoding="UTF-8"?>

<mule xmlns:dw="http://www.mulesoft.org/schema/mule/ee/dw" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:tracking="http://www.mulesoft.org/schema/mule/ee/tracking" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
    xmlns:spring="http://www.springframework.org/schema/beans" version="EE-3.7.3"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

     <http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/>
    <http:request-config name="HTTP_Request" protocol="HTTPS" host="apisandbox.openbankproject.com" port="443" basePath="/obp/v2.0.0" doc:name="HTTP Request Configuration"/>
    <flow name="account-balance-flow">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/" allowedMethods="GET" doc:name="HTTP"/>
        <http:request config-ref="HTTP_Request" path="/banks" method="GET" doc:name="HTTP"/>
        <logger message="#[message.payload]" level="INFO" doc:name="Logger"/>
    </flow>
</mule>
