You might have got a traceback which would tell you where precisely
the problem was detected. Looking the the code there (Python is "Open Source";
thus, you can look at code) will tell you what apparently went wrong.


"extra data" suggests to me that your JSON input may be invalid.

"1 2", for example could cause such a problem, because it contains
two integers (not a single one) without a containing container.
