Not able to set validDomains inside the manifest of app in Microsoft registered app

I want to use deeplinks to open a task module, acc to the documentation, i formed the deep link url as

https://teams.microsoft.com/l/task/b7636409-8e1a-40c0-b80a-7ea4bafdfcce?height=1000&width=1000&title=Preview&url=https://user-docviewer-testing.sentieo.com/?docid=61499c54f8fe3611c2738325&redirect=docviewer&src=app

the documenation further states that this url mentioned inside deeplinkurl should be under validDomains of the app manifest, when i tried editing that, got an error in case of both list type validDomains and string type validDomains ...

What would be the right approach to proceed with this?
