Using Power Shell to update dataset parameter -Need help

[roncruiser]

Hi Everyone!
From the Power Shell command line interface, I run the commands below.  No errors are thrown but the Power BI service dataset parameters in My Workspace do not change to the new values.
Can someone please review the script  to see if I am missing something else? Maybe I am missing something.
Maybe adapt the script to try on your side and see if it runs for you.
There's documention online suggesting updating dataset parameters work.

I think maybe I am missing some access permissions to do this.  I'm unsure.
Seeking help.

Thank you!
Note: Copilot suggested inserting this in place of the variable below:
$urlUpdateParams = "https://api.powerbi.com/v1.0/me/datasets/d62b1e0c-9060-4ecf-9994-ccd995d52693/parameters"
This doesnt work either.

$urlUpdateParams = "https://app.powerbi.com/groups/me/datasets/d62b1e0c-9060-4ecf-9994-ccd995d52693/parameters"


$body = '{
  "updateDetails": [
    {
      "name": "DirectPath_NonOneDrive_JSON",
      "newValue": "\\new\source\folder\path"
    },
    {
      "name": "Start Load Date_JSON",
      "newValue": "2025-02-10"
    },
    {
      "name": "End Load Date_JSON",
      "newValue": "2025-03-30"
    }
  ]
}'

$content = 'application/json'

Invoke-PowerBIRestMethod -Url $urlUpdateParams -Method Post -Body $body -ContentType $content

Thanks! I ran the scripit with the changes in the URL.

The errors suggest there is an issue with the last line of the script.
Two errors: One with AggregateException and the other with Exception.
Anyone know what could be the issue?  -Seeking help
