The attribute seek_position is sent with the Seek Start and Seek End events. The function sendMediaMessage while filtering attributes skipped seek_position because of the data type Float (Double) expecting the String type.
The value comes from the parameter position with predefined double type. I think it was mistakenly not converted to the String the same way as in the body of another function like logBufferStart.
Please, see the screenshot attached and consider converting to String the position attribute value to fix the issue with the skipped seek_position attribute.
