Flow action code snippet is not working on client side

[Saurav Bhardwa2]

Hello,

I am trying to use the flow action on onChange Client script, but I am getting this error in the console

" Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'status')"

Below is the script I am using 

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

(function() {
var site = '/sites/testsitesnow';
var dl = 'testinte';
var inputs = {};

inputs['tenant'] = { // GlideRecord
table: 'sn_sp_spoke_tenant',
sys_id: '34ba452c1bff6990ff7b20ecac4bcbe9',
};
inputs['site_relative_url'] = site; // String
inputs['document_library_relative_url'] = dl; // String
inputs['folder_location'] = ''; // String

GlideFlow.startAction('global.get_folders_inside_folder', inputs)
.then(function(execution) {
return execution.awaitCompletion();
}, errorResolver)
.then(function(completion) {

var status = completion.status;

// Available Outputs:
var outputs = completion.outputs;
// var status = outputs['status']; // Choice
var error_message = outputs['error_message']; // String
var filefolderlist = outputs['filefolderlist']; // String
var folder_count = outputs['folder_count']; // String
alert('test123 ' + folder_count);
});

function errorResolver(error) {
// Handle errors in error resolver
}
})();

}

May I know why I am getting this error?

@Saurav Bhardwa2 You are trying to user Server side code (script to trigger the flow) inside a client script which will not work.

I recommend you to create a Script Include which will have a method, call this script include and method using GlideAjax. Following is an example.

Here is the code for client script.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}

var ga = new GlideAjax('HelloWorld'); // HelloWorld is the script include class 
ga.addParam('sysparm_name','triggerFlow'); // helloWorld is the script include method 
//ga.addParam('sysparm_user_name',"Bob"); // Set parameters for flow here
ga.getXML(HelloWorldParse);  /* Call HelloWorld.helloWorld() with the parameter sysparm_user_name set 
      and use the callback function HelloWorldParse() to return the result when ready */

// the callback function for returning the result from the server-side code
function HelloWorldParse(response) {  
   var answer = response.responseXML.documentElement.getAttribute("answer"); 
    alert(answer);
}
}

Here is how you can prepare a client callable script include.

var HelloWorld = Class.create();
HelloWorld.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {

    triggerFlow: function() {       
        (function() {
var site = '/sites/testsitesnow';
var dl = 'testinte';
var inputs = {};

inputs['tenant'] = { // GlideRecord
table: 'sn_sp_spoke_tenant',
sys_id: '34ba452c1bff6990ff7b20ecac4bcbe9',
};
inputs['site_relative_url'] = site; // String
inputs['document_library_relative_url'] = dl; // String
inputs['folder_location'] = ''; // String

GlideFlow.startAction('global.get_folders_inside_folder', inputs)
.then(function(execution) {
return execution.awaitCompletion();
}, errorResolver)
.then(function(completion) {

var status = completion.status;

// Available Outputs:
var outputs = completion.outputs;
// var status = outputs['status']; // Choice
var error_message = outputs['error_message']; // String
var filefolderlist = outputs['filefolderlist']; // String
var folder_count = outputs['folder_count']; // String
gs.info('test123 ' + folder_count);
});

function errorResolver(error) {
// Handle errors in error resolver
}
})();

    },
    type: 'HelloWorld'
});

Please make appropriate changes in the above script according to your context and then you will be able to call flow from client script by making the suggested changes.

Hey Saurav,

Sandeep's reply is correct. I just want to add that I would think carefully before doing this from a client script. Much better to move this to an after or async business rule or even better, just set a flow to trigger on the state change.
