javax.net.ssl.SSLHandshakeException when using specmatic proxy and https host

[cduartelulo]

Hi guys,

I'm new using specmatic, I'm interested in Specmatic proxy to generate contracts, I have a private API secured by Mutual TLS, where is necessary to use a p12 certificate. The Specmatic proxy is started using the following command:

specmatic proxy --debug --target https://path/to/api/stage --port 9001 ./contracts

The proxy server starts correctly, however, when the proxy receives traffic an error is raised:

Received fatal alert: certificate_required javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_required at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:131) at java.base/sun.security.ssl.Alert.createSSLException(Alert.java:117) at java.base/sun.security.ssl.TransportContext.fatal(TransportContext.java:365) at java.base/sun.security.ssl.Alert$AlertConsumer.consume(Alert.java:293) at java.base/sun.security.ssl.TransportContext.dispatch(TransportContext.java:204) at java.base/sun.security.ssl.SSLTransport.decode(SSLTransport.java:172) at java.base/sun.security.ssl.SSLEngineImpl.decode(SSLEngineImpl.java:736) at java.base/sun.security.ssl.SSLEngineImpl.readRecord(SSLEngineImpl.java:691) at java.base/sun.security.ssl.SSLEngineImpl.unwrap(SSLEngineImpl.java:506) at java.base/sun.security.ssl.SSLEngineImpl.unwrap(SSLEngineImpl.java:482) at java.base/javax.net.ssl.SSLEngine.unwrap(SSLEngine.java:679) at org.apache.http.nio.reactor.ssl.SSLIOSession.doUnwrap(SSLIOSession.java:278) at org.apache.http.nio.reactor.ssl.SSLIOSession.decryptData(SSLIOSession.java:507) at org.apache.http.nio.reactor.ssl.SSLIOSession.isAppInputReady(SSLIOSession.java:550) at org.apache.http.impl.nio.reactor.AbstractIODispatch.inputReady(AbstractIODispatch.java:120) at org.apache.http.impl.nio.reactor.BaseIOReactor.readable(BaseIOReactor.java:162) at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvent(AbstractIOReactor.java:337) at org.apache.http.impl.nio.reactor.AbstractIOReactor.processEvents(AbstractIOReactor.java:315) at org.apache.http.impl.nio.reactor.AbstractIOReactor.execute(AbstractIOReactor.java:276) at org.apache.http.impl.nio.reactor.BaseIOReactor.execute(BaseIOReactor.java:104) at org.apache.http.impl.nio.reactor.AbstractMultiworkerIOReactor$Worker.run(AbstractMultiworkerIOReactor.java:591) at java.base/java.lang.Thread.run(Thread.java:840)

I'm stucked, I tried the following commands:

1. java -jar specmatic.jar proxy --debug --httpsKeyAlias "alias" --httpsKeyStore="/path/to/certificate/certificate.pfx" --httpsKeyStorePassword="password" --target=https://path/to/api/stage --port=9001 ./contracts

2. java -Djavax.net.ssl.keyStore="/path/to/certificate/certificate.p12" -Djavax.net.ssl.keyStorePassword="password" -jar specmatic.jar proxy --debug --target https://path/to/api/stage --port 9001 ./contracts

None of these work.

I really appreciate your help, we are very interested in using specmatic proxy, stubbing and other features.
