Hi,

I am getting the below error when I try to add an app to the site. I am using SharePoint Document Library for deploying the SPFx webpart in tenant. There are no errors when packaging or uploading the package to App Catalog.

But I am getting unexpected error when I add the app to the site. Below is the error from the ULS Logs. Can suggest some approach on how to resolve this?

Application error when access /_layouts/15/addanapp.aspx, Error=VAlue cannot be null. Parameter name: appId

    The issue resolved when I restarted all the servers. But it keeps occurring intermittently. We are still not able to resolve this permanently.
