I have raised an issue on their github page, but I haven't got any help there so far, hence I am turning to Crazyflie community to help me out.Unknown substitution command [eval enable_state_estimator == false]. Valid commands are ['find', 'env', 'optenv', 'anon', 'arg']
The traceback for the exception was written to the log file
I have followed all instruction steps mentioned in CrazyS github page multiple times, and infact I am able to launch different examples from their rotors_gazebo/launch folder. Its just with this particular launch file (crazyflie2_hovering_example) that I am having issues. So I am suspecting that it has something to do with this particular launch file, instead of prob being in my installation.
Secondly, the command mentioned in error message (eval enable_state_estimator == false), I can see this command in crazyflie2_hovering_example launch file at line# 34, so that makes me suspect this particular file more instead of installation, and sourcing bash commands.
I am copying line# 34 from crazyflie2_hovering_example for your reference below. Appreciate any help you can provide. Regards
