using filter.whitelist for nested value

[fadlymutil]

Hi There,

i am having problem when using configuration filters.whitelist for nested value,

my json document value part ;

"resPayload": [
  "{ \"timestamp\":1611882445, \"status\":200, \"errors\":{ \"identity_photo\":\"invalid\" }, \"data\":{ \"name\":true, \"birthdate\":true, \"birthplace\":true, \"address\":\"M*MP*NG\",\"selfie_photo\":80}}"
]

when i use this configuration, i got all value from resPayload field,
"filters.whitelist" : "apiName;resPayload",

but when i do this, i only get value apiName field, none from resPayload field
"filters.whitelist" : "apiName;resPayload.status",

how do i get only some field value i needed from resPayload

anyone can help me?
really appreciate your response.

Hi,
The problem is that resPayload is not a nested json document, but it is an array of strings.

For this reason, you cannot get resPayload.status

Hi Dario,

is it still possible to filter resPayload ? can you share how to do it?
for now i get all the value of resPayload, and cost large size of messages transfered to kafka,
it will be great if i can take out the field i dont needed which has large size (images)

thanks.
