Plugins: Uncaught (in promise) Error: Cannot execute a command without a runtime: selectedText

[ambrt]

This started to happen on 1.6.6, was working in 1.5.14

const selectedText = await joplin.commands.execute('selectedText');

Same is happening for replaceSelection.
Both on Ubuntu 18 and Windows 10.
