@Jenny Augusthy
Thank you for your post!
Based off your issue, I reached out to my team for inputs, and since you're using the ISIM service on Azure we'd recommend reaching out to the IBM Security Community regarding this, so their experts can look into your issue as well.
Error Message:
The certificate issued .... is not trusted; internal cause is: java.security.cert.CertPathValidatorException: Certificate chaining error'
From the error message, it looks like your certificate isn't trusted. A 'certificate chaining error' occurs when the provided chain of certificates cannot be validated.
Troubleshooting steps:
For more info - Certificate chaining errors in an HTTPRequest node
1) Verify that your truststore contains the proper 'signer certificate' for the certificate chain provided by the backend webservice.
Note
- If the proper signer certificate(s) exist in the truststore, then the handshake should complete. If not, you should confirm that all required certificates are present in the keystore of the webservice that WMB/IIB is communicating with. You may need to recreate the keystore with 'keytool' using the "genkey" option and re-import your application certificates if you are missing any components of the certificate chain.
