=== Error Message [[http-status-code-symbols]]

It is recommended to avoid using the StandardError exception when rendering error messages in the code, as this may capture an unintended and controlled error.
Instead, it is suggested to capture specific errors or send a customized standard error message.
This ensures more accurate and effective exception handling in the program.

[source,ruby]

# bad
...
rescue StandardError => e
render json: {error_msg: e.message}
end
...
# bad - usign in flash message
...
rescue StandardError => e
flash[:error] = e.message
end
...
# good
...
rescue StandardError => e
render json: {error_msg: 'Error in the application'}
end
...
# good

rescue ParticularError => e
render json: {error_msg: e.message}
