I have just added workaround of this bug in by code. And now it 
is working and returns backtrace

string[] getBacktrace(Throwable ex)
{
	import std.conv: to;
	import core.exception: OutOfMemoryError;

	string[] backTrace;
	try {
		foreach( inf; ex.info )
			backTrace ~= inf.to!string;
	} catch( OutOfMemoryError exc ) {} // Workaround for some bug in 
DefaultTraceInfo.opApply
	return backTrace;
}

auto errorToJSON(Throwable ex)
{
	import std.json: JSONValue;

	return JSONValue([
		"code": JSONValue(1),
		"message": JSONValue(ex.msg),
		"data": JSONValue([
			"file": JSONValue(ex.file),
			"line": JSONValue(ex.line),
			"backtrace": JSONValue(getBacktrace(ex))
		])
	]);
}
