It sounds like you are using SharePoint 2019? The error could be several issues. This article walks through several possible solutions.

Thanks for you reply, I saw this article befoe. I tried to follow the article
The article first subject was correct it was enabled.

The second theme of the first part was correct.

Looks like the article put two commands together by mistake. Split the commands into the following:

$sa = New-SPSubscriptionSettingsServiceApplication -ApplicationPool 'SharePoint Web Services Default' -Name 'Subscriptions Settings Service Application' -DatabaseName 'Subscription'

New-SPSubscriptionSettingsServiceApplicationProxy -ServiceApplication $sa 

That should get you through the next step. Good Luck

Hi,

Thanks again for your reply. I tried your guide  unfortunately I got this error in both commands 

I have a question is it posible  to use spfx in sharepoint 2019 on premise? because most tutorials I saw there were about sharepoint online?

Best Regards,
