I am getting this error when running ReimproveJs

Uncaught (in promise) Error: Error when checking : expected dense_Dense1_input to have shape [null,12] but got array with shape [1,14].

This error is not happening directly but after 5 seconds of it working. its called by academy.step My part, only added inputs:

let inputs = [speed,turn,sensor1Dist,sensor2Dist,sensor3Dist];          // Need to give a number[] of your inputs for one teacher.
        let result = await academy.step([               // Let the magic operate ...
        {teacherName: teacher, agentsInput: inputs}
        ]);
