how can I display OptionList process variable in Select widget in bonitasoft

Good morning

I use bonitasoft community edition version 2022.1

i wonder if can i display OptionList process variable in Select widget in bonitasoft?

I have used this API in form to retrieve my variable called outcome :

../API/bpm/caseVariable/{{task.caseId}}/outcome

caseVariable: ../API/bpm/caseVariable?p=0&c=10&f=case_id={{task.caseId}}

the result of this is:

{"case_id":"12078","name":"outcome","description":"","type":"java.lang.String","value":"house"}

and this is the configuration of my OptionList:
