It is due to very large number of records you are trying to serialize, which occupies large memory. Solutions which I have found for this error as directly writing to the documents using StreamWriter(JsonWriter or TextWriter).

If you have Object use TextWrite

using (TextWriter textWriter = File.CreateText("LocalJsonFile.json"))
{
    var serializer = new JsonSerializer();
    serializer.Serialize(textWriter , yourObject);
}

If you have string use StringWriter

  StringBuilder sb = new StringBuilder();
  StringWriter sw = new StringWriter(sb);

  using(JsonWriter textWriter = new JsonTextWriter(sw))
  {
     var serializer = new JsonSerializer();
     serializer.Serialize(textWriter, yourObject);
  }
