Ah, you’re totally right! I forgot about that.
Here is the leaked shooting schedule for those interested. http://millenniumfalcon.com/phpbb/viewtopic.php?t=9790
Definitely more focus on “the sword”, is the map even mentioned? I know there were rumors that the map was somehow in the lightsaber as well. But maybe Leia thought she could use the lightsaber to find Luke through the Force. I guess sort of like a search hound can find people by the scent of their clothing? Hahaha.

EDIT: There is one item in the schedule that reads:
INT DAY - 337 - RESISTANCE BASE - MAP ROOM • C3PO, R2-D2, and BB-8 solve the puzzle together.
But I think that is the only hint that there might’ve been a map during this point in the process.

Also if you want avoid Episode IX Spoilers I would suggest not reading through that either.
