IDN Form Search Query

Hi Team,

I am trying to get use form field search query to load identity drop downs. When i use predefined it’s loading properly no issue. When I try to use inline variable(one of field value) it’s throwing 400 bad request error.

When i used in label it’s working properly: {{$.form.data.[technical key of the form element]}}

when i use in search it’s not working: attributes.: {{$.form.data.[technical key of the form element]}}

Is there any suggestion can i get it to over come this issue.

Regards,
Naresh
