Example of a low-code module with a bug
- Navigate to the workspace "pjstips".
- Click New/Module File.
Click Edit/Source, to bring up the Source view.
- Clear the current default code, and enter the code below.
Code Block language js { "routines": [ { "name": "routine1", "inputs": [ { "type": "decimal", "ibmiLength": 4, "name": "custno", "ibmiDecimals": 0 } ], "outputs": [ { "type": "string", "ibmiLength": 30, "name": "name" } ], "steps": [ { "text": "Consume REST service", "answers": { "plugin": "Custom:web-service", "uri": "http://localhost:8081/run/pjstips/pjstips_02_3", "method": "POST", "headers": "{\"Content-Type\": \"application/x-www-form-urlencoded\"}", "body": "{\n \"custno\": input[\"custno\"]\n}", "json": true, "auth": "", "capture_response": true, "capture_on_error": false, "capture_as": "Value", "specific_property": "", "destination": "Work variable", "work_variable": "myres" } }, { "text": "Set Module output", "answers": { "plugin": "Program Data:set-module-output", "module-output-values": { "name": "myres[\"name\"]" } } } ] } ] }- Click Edit/Design, to bring up the Design view.
- Click Home/Save As, and save as pjstips_04_1.module.json.
- You've created a low-code module, as shown below, with a routine named "routine1" that:
- Takes an input parameter of "custno".
- Uses plug "Consume REST service" to issue a POST request to URL http://localhost:8081/run/pjstips/pjstips_02_3 (created in a previous example).
- The input "custno" is specified in the "body" of the POST request.
- The returned JSON object from the REST web service is saved in a work variable named "myres".
- The value of myres["name"] is used to set the output value output["name"].
- But, it has a bug; we'll learn how to debug this problem.
