@Dheeraj Gupta As of now JSON is converting to string while compilation and crosses the max length of string. So, that is why this error is occurring.

Have you tried to split your variable in various variables to avoid the string length limitation?

XData VariableName1 [ MimeType = application/json ] {}

XData VariableName2 [ MimeType = application/json ] {}

...

XData VariableNameN [ MimeType = application/json ] {}

You can declare the Property to %Stream.GlobalCharacter and you can use code function and Write the content in the variable example are the below commands. It works for me.

Example:

Property Content As %Stream.GlobalCharacter;

Transformation in DTL :
Do target.Content.Write( source.ClinicalReport.content)

xData block data's are basically stored the as a stream object in the class definition. If this is a property oriented then create a stream property %Stream.GlobalCharacter and store the values.
