Hi, in PG-14, how do I delete the keys "dunsNumber": "NaN":

{ "sessionId": "ce6fc9d0-5923-4d71-9f7e-ae60f35c45d6", "details": [ {
"keyInformation": { "dunsNumber": "NaN", "organizationType": "LIMITED_COMPANY"
} }, { "keyInformation": { "dunsNumber": "123", "organizationType":
"LIMITED_COMPANY" } } ], "nisse": 123 }

So that the result becomes:

{ "sessionId": "ce6fc9d0-5923-4d71-9f7e-ae60f35c45d6", "details": [ {
"keyInformation": { "organizationType": "LIMITED_COMPANY" } }, {
"keyInformation": { "dunsNumber": "123", "organizationType": "LIMITED_COMPANY"
} } ], "nisse": 123 }

Thanks.

Hi Andreas, this works for me.
