Here I processed a usual txt web content but Merlin doesn't actually access to it. Then I uploaded it in txt but it also could not access to it.

I disabled and reloaded Merlin plugin, it didn't help either.

Maybe this link supports the troubleshooting: https://extension.getmerlin.in/chat/share/c2dea2f2-936d-458e-aae3-7e144d2347d1
