I try the Large data Save in FHIR server in Binary Resource but it's failed 

Methed: Post , URL: fhirservers/fhir/r4/Binary 

I hit the API but the record not save and same API but base64 data length is 3 lac than it's save without faile.

I pass data on this formet

{

  "resourceType" : "Binary",

  // from Resource: id, meta, implicitRules, and language

  "contentType" : "<code>", // R!  MimeType of the binary content

  "securityContext" : { Reference(Any) }, // Identifies another resource to use as proxy when enforcing access control

  "data" : "<base64Binary>" // The actual content

}

I got this Response is 

{

    "resourceType": "OperationOutcome",

    "issue": [

        {

            "severity": "error",

            "code": "exception",

            "diagnostics": "5002",

            "details": {

                "text": "ObjectScript error: <MAXSTRING>%GetNext+2^%Iterator.Object.1"

            }

        }

    ]

}

How to fix this, or what is the solution for that? 

Using a WSDL and the SOAP wizard I created a WebServiceClient, and Operation to send an encoded message to a Vendor. But the vendor is now sending back an HL7 in the SOAP response.

I tried updating the Operation to Extend EnsLib.HL7.Operation.ReplyStandard, but still use the EnsLib.SOAP.OutboundAdapter. When I did this it broke my Operation and would not compile with the following error...

ERROR #5478: Keyword signature error in osuwmc.Nutrition.HL7SoapOperation:Method:SendMessage, keyword 'method argument/s signature' must be 'EnsLib.HL7.Message,EnsLib.HL7.Message,%Library.String' or its subclass

  > ERROR #5030: An error occurred while compiling class 'osuwmc.Nutrition.HL7SoapOperation'

Detected 1 errors during compilation in 0.015s.

The WebServiceClient is expecting "SendMessage"

Set tSC = ..Adapter.InvokeMethod("SendMessage",,pRequest.key,.encodedMessage)

So how do I get the Operation to send with the Data Class Structure they require but receive an HL7 ACK back to parse out and error if they send back an AR, AE, CR, etc...

We are looking for a way that if we receive an HL7 ACK AR response to ensure that the message keeps sending.
