SSL Certificate Issue Although Adding Open API certificate to Inteelij Idea

[selmantayyar]

My request to inspect the code fails with the error below on Intellij Idea:

"PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"

I have added Open API certificate after downloading it to Intellij Idea via Tools-> Server Certificates.

Plugin Settings below:

Please advise.
