Why would you want to send the InputData as an array here? Why not just send it as a string? Let json.loads(X) do the searlization in the python script.

All along we got an understand that your csv file has all the input and output data and probably your pipeline does the inference. We do not know what your joblib pipeline looks like. What you are trying to achieve and what is the output you are looking for. I think these are very important. Without a proper question, it is next to impossible to debug such problems remotely.
