There are many questions asking for help with the exact same error. Many questions. The best way to search for a solution is to use Google with the site operator and answers.ros.org. For example, go to Google and in the search bar enter:

<error> site:answers.ros.org

and Google will give you results using only this site! (Note: replace <error> with your error.)

Here's the search results for your error.

I had same issues with communicating to STM32 controller through ROS-noetic and rosserial-Mbed.

Here, the issue is with the version of the 'rosrun python'.

I installed python3 and obviously, did sudo update that fixed my problem.
