"Invalid Jason" when running Python code on Tableau to decompose a time serial data about tabpy HOT 2 CLOSED

JSON doesn't support NaN which your code returns so it fails to serialize.

The workaround would be to replace NaN with None.

You can do so by replacing the line of code where you convert to list with the following

y=list(np.where(np.isnan(x.resid), None, x.resid))

If you'd like to see intermediate results in your code (e.g. you could see NaNs in the result set this way), you can put print statements in your SCRIPT calculation. It will print to your console window from which you started TabPy.

I hope this helps.
