Indeed. A total mess! I was writing [1], [2] and [3], in the same script in order to evaluate all methods to parse a json input, then I made confusion with variable names.
I must avoid that bu commenting the code I write. Thanks
Btw, after I've cleaned the snnipet and added "package require json", the error is gone. https://iurix.com/ctree/import-sample
