Hi all, Trying to call a rest service sitting behind https. When using something like Postman I can get the expected response: [ { "code": "1", "description": "Venter" }, { "code": "2", "description": "Camp Master" } ] When I implement this in the modeler I get an error trying to process the response String into a mapping: com.mendix.modules.microflowengine.MicroflowException: org.codehaus.jackson.JsonParseException: Unexpected character ('M' (code 77)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at [Source: java.io.ByteArrayInputStream@44da5e49; line: 1, column: 2] at Trailer.IVK_CallWS_GetTrailerMakes (Import

I have included the Content-Type : application/json header. Any ideas?

You could store the response in a string. Parse the first part of the message so you get a nice JSON string. Then use `import mapping` action to import that JSON string.

It looks to me that an error is given because the error points to the first 'M' character of MD characters reply with all kinds of charachters before the JSON data formated data in the yellow box is given. Normally this 'prefilled' string data should not be given with a JSON response. Depending if more non-JSON data is retrieved in the JSON string you can try to remove it before parsing it as JSON import data.
