@Kyriacos Thank you for reaching out to Microsoft Q&A, apologize for the inconvenience caused on this.

If you are trying to pass the resource id of the webapp then you need to use the parameter --ids in az webapp deploy cmdlet instead of --id refer to this az web app deploy cmdlet documentation to know more about the optional parameters supported by this cmdlet.

I have tried to reproduce this behavior in my environment (running with AZ cli version 2.43.0 and webapp extension version 0.4.0) by creating 2 webapps (running on windows & Linux app service plan) using the az webapp deploy cmdlet I am able to deploy the static file to the webapp without any issue as shown below.

Feel free to reach back to me if you have any further questions on this.
