Hi Community,

I am getting the following error while trying to read from PDF file.

Reason:  
org.codehaus.groovy.runtime.InvokerInvocationException: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I have gone through the solutions available in [Stackoverflow](https://stackoverflow.com/questions/9619030/resolving-javax-net-ssl-sslhandshakeexception-sun-security-validator-validatore). By looking at the solution, it looked like the certificates were not installed. But I have checked and it is installed and still showing this error message. Can anyone please help me on this.

@suvankar.chandra

you have to install the certificate to the katalon jre.

if you added the certificate to java inside C:\Programing files\Java\jdk or jre it won’t reflect in katalon studio

you have to add the certificate to the katalon installation location which is under the following path

C:\Users\your user name.katalon\packages\Katalon\_Studio\_Windows\_64-8.6.6\Katalon\_Studio\_Windows\_64-8.6.6\jre\lib\security

please refer to my workaround here

Solution: After updating/installing (now katalon is downloading as an exe) to the new katalon version in the JRE file under the C:\Users\userName.katalon\packages\Katalon\_Studio\_Windows\_64-8.6.8\Katalon\_Studio\_Windows\_64-8.6.8\jre\lib\security\cacerts SSL Certificate is missing To add that if you are using lambda test/ Pcloudy/ Browser stack/Kobiton/sauce labs you need to add the certificate to …
