I am using WSO2 API Manager 2.6.0 and configured Pre packaged Identity Server 5.7.0 as Key Manager. When I create an Application in API Store and generate keys I can see that Service Providers are getting created in Identity Server. Also I am able to obtain token using the generated consumer id and secret. However when I pass that token to my APIs I am getting unclassified authentication error. Below is the exception that I can see in the logs,
ERROR - APIAuthenticationHandler API authentication failure due to Unclassified Authentication Failure org.wso2.carbon.apimgt.gateway.handlers.security.APISecurityException: Error while accessing backend services for API key validation at org.wso2.carbon.apimgt.gateway.handlers.security.keys.WSAPIKeyDataStore.getAllURITemplates(WSAPIKeyDataStore.java:77) at org.wso2.carbon.apimgt.gateway.handlers.security.APIKeyValidator.getAllURITemplates(APIKeyValidator.java:791) at org.wso2.carbon.apimgt.gateway.handlers.security.APIKeyValidator.doGetAPIInfo(APIKeyValidator.java:639) at org.wso2.carbon.apimgt.gateway.handlers.security.APIKeyValidator.findMatchingVerb(APIKeyValidator.java:573) at org.wso2.carbon.apimgt.gateway.handlers.security.APIKeyValidator.getResourceAuthenticationScheme(APIKeyValidator.java:357) at org.wso2.carbon.apimgt.gateway.handlers.security.oauth.OAuthAuthenticator.authenticate(OAuthAuthenticator.java:127) at org.wso2.carbon.apimgt.gateway.handlers.security.APIAuthenticationHandler.isAuthenticate(APIAuthenticationHandler.java:210) at org.wso2.carbon.apimgt.gateway.handlers.security.APIAuthenticationHandler.handleRequest(APIAuthenticationHandler.java:158) at org.apache.synapse.rest.API.process(API.java:325) at org.apache.synapse.rest.RESTRequestHandler.apiProcessNonDefaultStrategy(RESTRequestHandler.java:149) at org.apache.synapse.rest.RESTRequestHandler.dispatchToAPI(RESTRequestHandler.java:95) at org.apache.synapse.rest.RESTRequestHandler.process(RESTRequestHandler.java:71) at org.apache.synapse.core.axis2.Axis2SynapseEnvironment.injectMessage(Axis2SynapseEnvironment.java:303) at org.apache.synapse.core.axis2.SynapseMessageReceiver.receive(SynapseMessageReceiver.java:92) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:180) at org.apache.synapse.transport.passthru.ServerWorker.processNonEntityEnclosingRESTHandler(ServerWorker.java:337) at org.apache.synapse.transport.passthru.ServerWorker.processEntityEnclosingRequest(ServerWorker.java:383) at org.apache.synapse.transport.passthru.ServerWorker.run(ServerWorker.java:151) at org.apache.axis2.transport.base.threads.NativeWorkerPool$1.run(NativeWorkerPool.java:172) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: org.wso2.carbon.apimgt.gateway.handlers.security.APISecurityException: Error while accessing backend services for API key validation at org.wso2.carbon.apimgt.gateway.handlers.security.keys.APIKeyValidatorClient.getAllURITemplates(APIKeyValidatorClient.java:189) at org.wso2.carbon.apimgt.gateway.handlers.security.keys.WSAPIKeyDataStore.getAllURITemplates(WSAPIKeyDataStore.java:75) ... 21 more Caused by: java.lang.NullPointerException at org.wso2.carbon.apimgt.gateway.handlers.security.keys.APIKeyValidatorClient.getAllURITemplates(APIKeyValidatorClient.java:183) ... 22 more
Any help would be much appreciated.
