SOAP.OutboundAdapter HttpResponse doesn't handle large response [SOLVED]

Hi all,

Sorry to bother

I have a Business Object with SOAP.OutboundAdapter and it gets the response from a WebApi.

Following the sample Creating REST Services and Clients with Ensemble - Developing a REST Operation, I've done the call and it retrieves a JSon with the information. The result is a JSon with a Base64 content (at least 15000 bytes)

I've put a trace to check the content with $$$TRACE(tHttpResponse.Data.Read() I have a cut result (to 1200 character), so the JSonStreamToObject is not able to allocate the full result into a object.

is there any way to handle more character in HttpResponse or is about SOAP.OutboundAdapter configuration?

Best regards

mmm... I see

The name of the variable is under double quote, and I'm calling the variable directly. Let me check in my solution.

USER>set obj = ##class(%DynamicObject).%FromJSON("{""A_B"":""HELLO WORLD""}")
USER>w obj.A_B
W obj.A_B
^
<UNDEFINED> *B
USER>w obj."A_B"
HELLO WORLD

Hi all,

I've found the "ghost in the code". The problem was the JSon structure has some fields with "_" as part of the name of the property. When it tries to convert JSon to a class, this kind of name is not good for ensemble.

How have I solved? easy... replacing the content and remove all "_" (I'm sure that there is not values with "_")

    set content = tHttpResponse.Data.Read()
    $$$TRACE(content)
    $$$TRACE($LENGTH(content))
    
    set content = $REPLACE(content,"_","") // Remove all _ as part of the field name
    
    set objJson = ##class(%DynamicObject).%FromJSON(content)

    set b64 = objJson.Result.RES.DATA.DATAB64   // Instead of DATA_B64

Take care with this problem if you are developing Api and Cache

Best regards

There should not be a problem with underscores:

set obj = ##class(%DynamicObject).%FromJSON("{""a_b"":1}")
w obj."a_b"
>1

Thanks Eduard, my JSon has this underscore as part of the name of variable but is not supported (or it seems). With my workaround it works

Indeed underscore characters are fully supported in the new JSON API (%DynamicObject and %DynamicArray). Are you sure this is the only change you made?
