The above JSON payload contains special characters because the payload contains the data for different languages.

Since the payload is of different language based on the country code, so I am getting error while publishing the data to Anypoint MQ.

Please help me with this.

Answer 1

It seems like the payload is a valid JSON but Any point MQ doesn't like some characters. The error message should be clearer. I recommend reporting the issue to MulesSoft for further analysis. In the meantime you may be able to escape national characters as Unicode escapes (\uHHHH) using Java or Groovy code an see if that works.
