Unable to export, internal error, attempt to index a nil value
With the latest release of Adobe Photoshop Lightroom Classic CC v7.01 on a Mac, attempting to export JPGs to a subfolder, when selecting to overwrite the existing will for some files generate the error (translated from Spanish, so it might not be the exact string in the English version): Unable to export: An internal error has occurred: ?:0: attempt to index a nil value. There are other people posting for this error, but they are either years old or don't seem relevant, so I'm posting anew. Anyone got any ideas?
