Hi,
I have the following JSON String that needs to be deserialized:
{"localusers": {"mobile_number": ["Invalid mobile number"] , "password": ["Password must have at least 8 character(s)"] }}
I created a structure like this:
The Value under JSONFortiAuthenticatorRec is of data type Text Record list
And the JSONFortiAuthenticatorRecList is of data type
And the data type of the built in JSONDeserialize is of data type JSONResponseFortiAuthenticator Record list.
When I run it I get the error
Failed to deserialize JSON to JSONResponseFortiAuthenticatorRecordList: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'ssReporterB.RestRecords.JSONRCJSONResponseFortiAuthenticatorRecord[]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path 'localusers', line 1, position 14.
What am I doing wrong?
any help would be much appreciated.

Hi Alexei,
Why did you create the structure manually?
You should right-click on the structure folder
Then past your json in the popup-window, name the structure and you are good to go
Then you know you (de)serialize will work.
J thanks for your quick reply.
The structure provided above is a returned result of a scenario I'm testing.
So I did indeed what you stated.
and it generated the following:
I provided the JSONDeserialize with the structure1 as a record list
And I got the same result,
Failed to deserialize JSON to Structure1RecordList: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'ssReporterB.RestRecords.JSONRCStructure1Record[]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path 'localusers', line 1, position 14.
your json isn't a recordlist, simply have the datatype set to Structure1
J many thanks for your help.
It works for the scenario above, but the structure is a dynamic structure based on what produces an error it will provide them in an array, like
{"localusers": {"mobile_number": ["Invalid mobile number"] , "password": ["Password must have at least 8 character(s)"]
, "First name": ["First Name is mandatory"]
, ..........
......... }}
so I cannot have them static as the structure is being created like the one below
I tried to make the structure like this:
( the LocalUser I have renamaed it to Topic)
but It will store only the information of the mobile number, but it will not append the information of the password to the list.
Do you know how I can accomplish this?
OutSystems doesn't support what you want. The JSON attribute name must be an Attribute name in an OutSystems structure. If that's the JSON you get, you need to parse it manually.

Kilian thanks for your reply, to bad that we cannot use dynamic list structures.
Yes, it would be nice for these kind of use cases (I've seen them before), but as it is, like I said, you'll need to parse it yourself, unfortunately.
You can always create an idea (or look for a similar idea and upvote it :) )
