Can you provide further details about your strds and how you want to use t.rast.gapfill? What does t.info and t.rast.list show? Please note that t.rast.gapfill is not intended to fill holes in maps but interpolate full missing maps in between x other maps, that's why it needs to determine predecessor and sucessors. Take a look at the manaul page: https://grass.osgeo.org/grass76/manuals/t.rast.gapfill.html
