The basic issue is described here:
https://www.postgresql.org/docs/current/plpgsql-implementation.html#PLPGSQL-VAR-SUBST
"Since the names of variables are syntactically no different from the
names of table columns, there can be ambiguity in statements that also
refer to tables: is a given name meant to refer to a table column, or a
variable? Let's change the previous example to ..."
ERROR: column reference "Uuid" is ambiguous
LINE 3: ON CONFLICT ("Uuid")
Is occurring because there is ambiguity between:
"Uuid" text
in RETURNS TABLE and
"Lockers"."Uuid"
I would say the easiest way out of this is to change:
"Uuid" text --> "uuid_out" text
