Hello Experts,
I have a custom processor where I have below lines of code -
private ReadContext configJsonCtx = JsonPath.parse(configJsonString);
private List<Object> workFlows = configJsonCtx.read("$.Workflow");
this.workFlows.forEach((workFlowObj) -> {
try {
DocumentContext workFlow = JsonPath.parse(workFlowObj);
........
This is working fine with Nifi 16 and com.jayway.jsonpath.json-path:2.4.0 dependency.
But now I am trying to upgrade to nifi 24 and I am getting below error when I do that
Any idea what could be the reason and solution for the same.
