Observation data dimension error (numObservations)

Hello,

I've been trying to fix this issue for more than a week now however I can't crack it. When trying to run my simkulink model for reinforcement learning I get an error stating:

Error using rl.env.SimulinkEnvWithAgent>localHandleSimoutErrors (line 667)

Invalid observation type or size.

When running from simulink the error is the same. My code for the observation data is:

obsInfo = rlNumericSpec([3 1],...

'LowerLimit', [0 0 0]',...

'UpperLimit', [1 500 500]');

obsInfo.Name = 'observations';

obsInfo.Description = 'pulse, voltage error, integrated error';

numObservations = obsInfo.Dimension(1);

In my simulink model the observation signal has a dimension of 8; however whenever I try to modify my code to take this into account and have the dimensions match up - I get an error.

Does anyone have any advcie as to how to modify the matlab code such that the dimensions will match up? Or is this error perhaps a result of something else entirely! Any thoughts or ideas are more than welcome.

Best,

Abd

Apologies; for clarification the error could be due to the action signal diemsnions however the action signal dimension needs to be what it currently is set to (1) so I dont think this is where the issue is as the simulink error message takes me to code where the error is in the observation information.
