I am trying to pass the multiple URI params in the http request as follows:

    <http:listener-config name="HTTP_Listener_Configuration"

    host="localhost" port="8081" doc:name="HTTP Listener Configuration"

    connectionIdleTimeout="40000" />

<http:request-config name="HTTP_Request_Configuration1" protocol="HTTPS" host="" port="443" doc:name="HTTP Request Configuration" connectionIdleTimeout="300000" responseTimeout="50000">

    <http:basic-authentication username="user" password="123"/>

</http:request-config>    

<flow name="testFlow">

    <http:listener config-ref="HTTP_Listener_Configuration"

        path="/paypal" allowedMethods="GET" doc:name="HTTP" />

    <set-variable variableName="config" value="#[{'p1':'3054', 'p2':'child/Lines'}]" doc:name="Variable"/>

    <http:request config-ref="HTTP_Request_Configuration1" path="/resources/shipment/{p1}/{p2}" method="GET" doc:name="HTTP">

        <http:request-builder>

            <http:uri-params expression="#[flowVars.config]"/>

        </http:request-builder>

    </http:request>

</flow>

But this is giving me error as below:

Response code 404 mapped as failure.

Please let me know if any help can be provide!

It means that the url doesn't exist. Try to hit the url directly in postman before implementing in Mule. Since you wiped out the host="", I'll pretend it's example.com. My guess is that it's having an issue with p2. If you'd like to send the actual string, you'll need to URL encode the "/", which is %2F

So to test hit https://www.example.com/resources/shipments/3054/child%2FLines, with the Basic Auth for Authorization.

Postman: https://www.getpostman.com/apps

The issue i faced was unique to me, i tried this REST api call from SOAPUI and there it gave me the same error i.e. 404 not found so i compared it with POSTMAN request and found that Authorization header was the missing piece for this.
After adding this to http header it worked perfectly.

Please refer
https://docs.mulesoft.com/connectors/http/http-authentication

here are two solutions :
1. Add preemptive="true" in basic authentication configuration
The pre-emptive option passes the user name and password without waiting for a prompt from the server.

2. Add Authorization in the http:header value ="Basic dXNlcjoxMjM="
