Whenever I try to open process definition in drools , Getting the Below Error
Invalid credentials to load data from remote server. Contact your system administrator.
I have given all permissions to role permission to user but still this error shows up.
While many details from your problem are not clear, here is the bottom line of this issue.
You are logging into the business-central with user 'nithish'. This user, will be used in the remote REST requests to your kie server instance. This means that user 'nithish' needs to exists on the kie-server side as well - otherwise kie-server will not recognise that user, thus authentication will fail. He needs to be created there with the same password and same roles as are present on the business-central side. I would advise at least
kie-server, rest-all,admin
roles.
