Was trying to import survey via remote api using java but encountered the following error during execution:
{"id":null,"result":null,"error":"unable to decode malformed json"}

Using the following method:
post.setEntity( new StringEntity("{\"method\": \"import_survey\", \"params\": [\""+sessionKey+"\", \"" +readXML()+ "\", \"lss\", \"20170906_TEST1\", \"999999\"], \"id\": 1}"));

I tried importing the lss file via gui and was successful.
Do we need to filter any special characters in the lss file generated from lime?

Perhaps this thread can give some insight. Looks similar.

readXML() ? This don't update the xml readed ? You must send untouched xml.

Thank you DenisChenu for your reply and reminder about debug mode.
