Cannot deserialize the current JSON object - Why it happens when clicking on Azure App Service page ?

Question

When trying to open the AppService page it appear this message

An error occured when trying to fetch resources. Additional details from the underlying API that might be helpful: Please provide below info when asking for support: timestamp = 2020-12-17T17:02:59.4960450Z, correlationId = dde4cd76-1eff-409b-8a9b-f9b72eb2033c. (Code: BadRequest) An error occurred when deserializing the request body: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.IList`1[System.String]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.

Hi Ryan
Tried incognito and it does not happen. I am using a computer from my company and not sure is somethingelse is blocking it.
Google Chrome is up to date - Version 87.0.4280.88 (Official Build) (64-bit)

I had the same issue this morning trying to access my Automation Accounts portal using the latest Edge browser. Incognito mode works fine. I then cleared the browser history in my normal browser session and it started working again. It appears to be a browser caching issue.
