Fill in URL in a newly created reminder

Since macOS Catalina, Reminders.app offers the possibility to fill in an URL in a reminder.

Click the Info button, then add or change details.

Add a URL: Click the URL field, and type a web address.

I am trying, via Automator and with a bit of AppleScript, to create a reminder based upon a text in Chrome.
The goal would be, from a selected text in Chrome, to add a reminder with the URL of the page the selected text is coming from.

I am able to create the reminder properly, along with the name and the body, but I am struggling to fill in the URL field of a reminder.

I tried:

```
set url of new_reminder to tab_url
```
which errors with:

Reminders got an error: Can’t set URL of reminder id "x-apple-reminder://AB572176-9661-48FA-ADCF-795D0A912FED" to "https://stackoverflow.com/questions/ask".
```
set uri of new_reminder to tab_url
```
which errors with:

Reminders got an error: Can’t make uri of reminder id "x-apple-reminder://2564FAFB-3825-442C-AAD5-BCA17E354D1B" into type specifier.

The first error makes me wonder if the URL should not be type casted into an URL object somehow?
But I am a bit lost on what I should be trying from here.

The macOS version I am on is 10.15.5 (19F101).

Here is my current AppleScript:

on run {input, parameters}
    tell application "Google Chrome"
        set tab_name to get title of active tab of window 1
        set tab_url to get URL of active tab of window 1
        tell application "Reminders"
            set recipes to list "Recipes"
            tell recipes
                set new_reminder to make new reminder
                set name of new_reminder to tab_name
                set body of new_reminder to input
                (* set ??? of new_reminder to tab_url *)
            end tell
        end tell
    end tell
end run

Solution

Sadly, as of today 28 November 2022, the URL property is not accessible in the list of properties of a reminder that AppleScript can set — this was updated with the release of macOS Ventura, that didn't change the situation.

This is backed up by this piece of AppleScript, giving all the properties of a reminder:

tell application "Reminders"
    set reminder_properties to properties of first reminder
end tell

Given the reminder filled in as in the question, example reminder

This piece of script yields the result:

{
  id:"x-apple-reminder://XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX", 
  creation date:date "Wednesday, 2 September 2020 at 19:49:45", 
  container:list id "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX" of application "Reminders", 
  priority:0, 
  name:"Test reminder", 
  remind me date:missing value, 
  completed:false, 
  modification date:date "Wednesday, 2 September 2020 at 19:50:41", 
  due date:missing value, 
  completion date:missing value, 
  flagged:false, 
  body:missing value, 
  allday due date:missing value
}

Where we can definitely see that the URL filled in the reminder is nowhere to be seen.

For what it's worth, I ended up doing this with Shortcuts.
