Workspace api method only works in console based application. For eg: Lightning console or Service Console . It won't work on Sales App.

From documentation:

This component allows you to access methods for programmatically controlling workspace tabs and subtabs in a Lightning console app.

I found that, depending on what level your tab is on this error will be thrown. If its not opened on the default tab, you wont see this error.
