    Hello guys, long time no see!

    I wonder did any of you experienced such issue, that running a script from CLI fails due to missing prototype functions? “isArray” or “indexOf” simply fails, while with UI it works as expected. Thus, my guess is that somehow its related with that UI can offer (maybe these libraries are embedded during GUI load)

    ReferenceError: Function Array.isArray

    In case you have any workarounds in mind – I would be happy to check them, as for now the only option I see is pre-defining those functions in the scripts – which I would be more than welcome to not do…

    In case if someone runs into the same issue, try to include files from this (or similar) location on your machine:
    C:\Program Files\Common Files\Adobe\CEP\extensions\CC_LIBRARIES_PANEL_EXTENSION_3_12_165-1\jsx
