Hi,
I’m trying to consume the camunda rest api which is Execute Filter List via postman. Below is the url, but I’m getting the below error while hitting the api.
[Preformatted text](https://workbench/process/workbench/engine-rest/filter/240C07D5-BA42-46C0-A78B-94FD3B7718B2/list)

{
    "type": "ProcessEngineException",
    "message": "Unable to invoke method 'taskAssignee' on class 'org.camunda.bpm.engine.impl.TaskQueryImpl'",
    "code": 0
}

I have the BPMN which contains candidateGroup as below.

in database the table ACT_RU_FILTER contains the query columns below.

{"taskCandidateGroupInExpression":"${ currentUserGroups() }","includeAssignedTasks":false,"keys":["FourEyeCheck"]}

I tried to add the basic authentication mechanism properties in application.properties file like below.

camunda.bpm.run.auth.enabled=false
camunda.bpm.run.auth.authentication=basic

Below is the postman snippet that hits the rest api.

We are using camunda version 7.21.3-ee, spring boot version 3.4.4.

Can anybody please assist here.

Thanks,
Ram

Since you’re using EE, I would suggest opening a ticket in the support portal.

They will likely want to see logs from the server, to understand why it couldn’t develop a list of users.

Hi @Ramanaiah,

Please make sure to enable authentication by setting the following property:

camunda.bpm.run.auth.enabled=true

Hi @hassang I have enabled that property in .props file.

camunda.bpm.run.auth.enabled=true

camunda.bpm.run.auth.authentication=basic

But still no luck.
