float error while using a float - custom messages

edit

Hello all,

I am receiving this error.

[example36-1]     self.age.year = 2022
[example36-1]   File "/home/user/ros2_ws/install/custom_interfaces/lib/python3.8/site-packages/custom_interfaces/msg/_age.py", line 131, in year
[example36-1]     assert \
[example36-1] AssertionError: The 'year' field must be of type 'float'

Only, I am using a float.

from custom_interfaces.msg import Age

...

    def on_shutdown(self):
        self.age.year = 2022
        self.age.month = 5
        self.age.day = 1
        self.get_logger().info('date this program was made : %s' %
                               self.age.day + '/%s' % self.age.month + '/%s' % self.age.year)

And if you'd like to see the age message type

float32 year
float32 month
float32 day

Pretty sure I compiled it correctly and stuff since when I run

user:~/ros2_ws$ ros2 interface show custom_interfaces/msg/Age
float32 year
float32 month
float32 day

It spits it out.
