Is your configuration file well indented? Like this:

plant_conf:
  P_from_grid_max: 9000 # The maximum power that can be supplied by the utility grid in Watts
  P_to_grid_max: 9000 # The maximum power that can be supplied to the utility grid in Watts
  module_model: # The PV module model
  - 'CSUN_Eurasia_Energy_Systems_Industry_and_Trade_CSUN295_60M'
  inverter_model: # The PV inverter model
  - 'Fronius_International_GmbH__Fronius_Primo_5_0_1_208_240__240V_'
  surface_tilt: # The tilt angle of your solar panels
  - 30
  surface_azimuth: # The azimuth angle of your PV installation
  - 205
  modules_per_string: # The number of modules per string
  - 16 
  strings_per_inverter: # The number of used strings per inverter
  - 1
  inverter_is_hybrid: False # Set if it is a hybrid inverter (PV+batteries) or not

And how are you passing your config to the docker run command?

It was a trivial probem. Command + S did now save in Visual Studio, so changes in config_emhass.yaml were not saved. Feeling stupid but it is what it is.
