Hi,
I have installed the Camunda on Redhat linux server and am able to start and open camunda on web browser.
I have deployed a bpmn on camunda successfully but when I am trying to start the process using http:///engine-rest/process-definition/key//start, am getting following exception,
Request your help here.
I have added the destination certificate to the keytool using below command,
keytool -import -v -trustcacerts -alias test123 -keystore /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64/jre/lib/security/cacerts -file /home/techm/test.crt
