Invalid frame ID "base_footprint" passed to canTransform argument source_frame - frame does not exist --- ros2 foxy

edit

Hi. I am using ekf package for robot localization. It seems working both Rviz and Gazebo simulation. However, I am getting some warning messages in the terminal that I could not solve it yet. The warning message is :

"[ekf_node-3] Warning: Invalid frame ID "base_footprint" passed to canTransform argument source_frame - frame does not exist"

My ekf configuration code is :
