Cannot get on-schedule Workflow to run Follow

Hi there,

I am on InCloud - and whatever I try, I cannot get this on-schedule Workflow to run. Any ideas?

var entities = require('@jetbrains/youtrack-scripting-api/entities');

exports.rule = entities.Issue.onSchedule({

title: 'Update-all-epicidforexports',

search: 'type:{User Story},Bug project:example1,example2 sprints: sprint34',

cron: '0 10 13 * * ?',

muteUpdateNotifications: true,

guard: function(ctx) {
return true;
},

action: function(ctx) {

var parent = ctx.issue.links['subtask of'].first();

console.log("start");

if (parent && parent.isReported) {
if (ctx.issue.EpicIDForExports != parent.id + ' ' + parent.summary) {
ctx.issue.EpicIDForExports = parent.id + ' ' + parent.summary;
console.log(ctx.issue.project.name + ' : Update custom field with parent issue id for ' + ctx.issue.id + ' done with ' + parent.id + ' ' + parent.summary);
}
} else {
if (ctx.issue.EpicIDForExports) {
ctx.issue.EpicIDForExports = null;
console.log(ctx.issue.project.name + ' : Clear custom field on ' + ctx.issue.id);
}
}

},
requirements: {
EpicIDForExports: {
name: 'EpicIDForExports',
type: entities.Field.stringType
}
}
});

The only thing it does, is copy epic link information to a custom field (to have the epic link in the exports). The query returns tickets when I search it in youtrack. There are no errors shown on the scheduled execution time. Code inspection shows no errors.

In this case I was expecting it to run today at 13:10 o clock.

Can anybody help me out?

Kind regards
