Issue creating schedules

Product: PowerShell Universal
Version: 2.7.0

When trying to create schedules via Universal PowerShell Module or the UI. We are receiving the following error.

Do you have a parameter that is a string array?

param([string[]]$arr)

I can reproduce a similar error but it’s not totally the same.

LiquoriChris · January 11, 2022, 8:46pm

I do not. It take 2 [string] params and a [bool].

Tracking here: Error creating schedule with a string[] in the parameters · Issue #826 · ironmansoftware/issues · GitHub

adam · January 11, 2022, 8:46pm

Ok. Thanks.

EDIT: This is a big day of me not reproducing stuff. I do not see this particular issue. Can you check in the F12 developer tools and see what request the browser is making? I’m curious about the JSON sent to the server.

LiquoriChris · January 11, 2022, 8:55pm

{
  "cron": "0 0 * * *",
  "continuous": false,
  "timeZoneString": "America/New_York",
  "parameters": [
    { "name": "Identity", "value": "<my user>", "type": "System.String" },
    { "name": "GroupName", "value": "Education", "type": "System.String" },
    { "name": "Remove", "value": "false", "type": "System.Boolean" }
  ],
  "credential": "Default",
  "script": "<my script>.ps1",
  "name": "test"
}

And also when I try to use Integrated to create the schedule in a dashboard, I am receiving:

Sequence contains no matching element

I’ve been using -AppToken without issue, but when I try to use AppToken I am getting a 500.

adam · January 11, 2022, 9:18pm

Thanks. I’ve opened issues for both of these.

I actually have integration tests pass for both these cases so I may need to make them a bit more robust. One thing that I notice is that they are not testing schedules with these types of parameters. That said, I’ve created a script with that param block and I don’t see this issue.

EDIT:

I’ve reproduced this issue while creating schedules through the cmdlets.

And I’ve noticed if I try to schedule a script that has no params with -Integrated, it does work.
