How does your plugin config look like?

        {
            indexPages: true,
        }],

Caught the same bug. I suppose, it's somehow connected with the Multidoc feature. When I add the plugin to a newly installed instance, everything works fine. But, once I place articles in the root folder next to /docs (and make some versioned), the build fails with this very error.
