[ekf_node-1] terminate called after throwing an instance of 'rclcpp::ParameterTypeException' [ekf_node-1] what(): expected [string] got [not set]

edit

Hello,

Thanks in advance for your help!

I'm having a nightmare trying to figure out what's wrong with my code. I just installed ros2 galactic and I'm running the code that works on ros2 foxy. When I launch the robot_localization package it works fine on ros2 foxy, but in galactic I'm having this error:

[ekf_node-1] terminate called after throwing an instance of 'rclcpp::ParameterTypeException' [ekf_node-1] what(): expected [string] got [not set]

I changed to galactic because It has a lot of improvements that are very useful for my thesis project so It would be much appreciated some help to get it to work in this distro.

Here is the screenshot of the terminal:

This is my configuration file:
