Failed to create PKIX path in WSO2 ESB
I am getting below exception in WSO2 ESB when calling REST APIs that are supposed to call twitter backside API. I followed the steps given in this blog post . The twitter security certificate has been successfully imported into the wso2 keystore. What is the reason for this? I am using wso2 esb version 4.8.1.

Export certificates
Go to https://YOUR_SERVER_HOST.com/ , click the lock icon in the address bar, go to the Connection tab, then click the Certificate Information link. In the "Certificate Viewer" select the "Details" tab and click the "Export" button and upload the certificate (YOUR_SERVER_HOST.com) to your preferred location.
Import to wso2esb "client-truststore" using the following commands
$ cd% WSO2_HOME% / repository / resources / security
$ keytool -importcert -file $ path / YOUR_SERVER_HOST.com.cer -keystore client-truststore.jks -alias "YOUR_SERVER_HOST.com"
Use password "wso2carbon" when prompted

I had a similar problem with another wso2 product. I have successfully imported the certificate to the store. It seems to reload the keystore on server reboot, so yoo will have to reboot the server (if you haven't already).
Also, there are 2 keystores, wso2carbon.jks (as I assume you are linking) and client-truststore.jks. You need to import it into client-truststore.jks.
Hope it helps.
Greetings
Matt
