I have created a SPFx Extension (Application Customizer - Tenant Scoped) and I have uploaded it to the App Catalog succesfully.
Now I'm trying to add it in a Site creating a UserCustomAction, but I'm getting the next error:
'ClientSideComponentId and ClientSideComponentProperties are not supported for actions that are not used for client-side extensions.'
This is the code for the creation of the UserCustomAction:
...
// var colCustomActions = cc.Web.UserCustomActions; // << also tried in the web
var colCustomActions = cc.Site.UserCustomActions;
var newCustomAction = colCustomActions.Add();
newCustomAction.ClientSideComponentId = new Guid(guidFromTheManifest);
newCustomAction.ClientSideComponentProperties = "";
newCustomAction.Update();
cc.ExecuteQueryRetry();
Any hints? Do you have an example of the code for the creation of the UserCustomAction?
Thank you very much in advance.
Best regards.
