Getting Error 'sun.security.provider.certpath.SunCertPathBuilderEception' while trying to hit an API from Java Gradle project

Question

I have built a java Gradle project from Intellij (Mac OS) for API Automation. When i try to hit the API, i am getting the below error.

'sun.security.provider.certpath.SunCertPathBuilderEception: unable to find valid certification path to requested target'

I have tried to

• Add the certificate to the keystore
• Added them on Service Certficates on Intellij.
• Updated the JDK to version 19

Still my issues is not resolved.

Can anyone suggest a resolution for this?
