The source filename 'map-functions.md' doesn't match the destination filename pattern 'tuple-map-functions.md'. The destination suggests these are 'tuple-map' functions, not just 'map' functions. Consider renaming the source to 'tuple-map-functions.md' for consistency, or update the destination to 'map-functions.md' if these are purely map functions.

Suggested change

	"map-functions.md"
