Error to convert JSON file into a QR-Code

Question

I'm trying to convert a json file into a qr code using pyqrcode

import tkinter as tk
from tkinter import filedialog
import json
import pyqrcode as qrcode

root= tk.Tk()
root.title('Convertitore CSV in JSON')

canvas1 = tk.Canvas(root, width = 300, height = 300, bg = 'lightsteelblue2', relief = 'raised')
canvas1.pack()

label1 = tk.Label(root, text='Tool Conversione File', bg = 'lightsteelblue2')
label1.config(font=('helvetica', 20))
canvas1.create_window(150, 60, window=label1)

def json_to_qrcode(jsonFilePath2, imageFilePath):
    with open(jsonFilePath2, 'w', encoding='utf-8') as jsonf:
        jsonReader = json.load(jsonf)
         
        qr = qrcode.QRCode(version = 1, box_size = 15, border = 5)
        data = jsonReader
        qr.add_data(data)
        qr.make(fit = True)
        img = qr.make_image(fill = 'black', back_color = 'white')
        img.save('Dieta.png')
        
jsonFilePath2 = filedialog.askopenfilename()
imageFilePath = filedialog.asksaveasfilename(mode='w', defaultextension=".png")

browseButton_CSV = tk.Button(text="     Importa JSON File     ", command=json_to_qrcode(jsonFilePath2, imageFilePath), bg='green', fg='white', font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 130, window=browseButton_CSV)

root.mainloop()

Here is an example of JSON file:

[
    {
        "Giorno": "Lunedi",
        "Tipologia": "Prima Colazione",
        "Alimento": "Fette biscottate",
        "Quantita": "3",
        "UDM": "fette",
        "Note": ""
    },
    {
        "Giorno": "Lunedi",
        "Tipologia": "Prima Colazione",
        "Alimento": "Latte",
        "Quantita": "200",
        "UDM": "g",
        "Note": ""
    }
]

When I try to run the code it gives to me this error: "TclError: bad option "-mode": must be -confirmoverwrite, -defaultextension, -filetypes, -initialdir, -initialfile, -parent, -title, or -typevariable"

How can I solve it? Thanks in advance.

Please provide the expected [MRE - Minimal, Reproducible Example](https://stackoverflow.com/help/minimal-reproducible-example). Show where the intermediate results deviate from the ones you expect. We should be able to paste a single block of your code into file, run it, and reproduce your problem. This also lets us test any suggestions in your context. [Include your minimal data frame](https://stackoverflow.com/questions/52413246/how-to-provide-a-reproducible-copy-of-your-dataframe-with-to-clipboard) as part of the example. Also provide the *entire* error message, including traceback. — Prune, Feb 27 '21 at 17:41

You are trying to pass wrong args for filedialog.asksaveasfilename() function.

you are using pyqrcode instead of qrcode. (you have written code regarding qrcode library)

 import tkinter as tk
 from tkinter import filedialog
 import json
 import qrcode

 root = tk.Tk()
 root.title('Convertitore CSV in JSON')

 canvas1 = tk.Canvas(root, width=300, height=300, bg='lightsteelblue2', relief='raised')
 canvas1.pack()

 label1 = tk.Label(root, text='Tool Conversione File', bg='lightsteelblue2')
 label1.config(font=('helvetica', 20))
 canvas1.create_window(150, 60, window=label1)


 def json_to_qrcode(jsonFilePath2, imageFilePath):
     with open(jsonFilePath2, 'r') as jsonf:
       jsonReader = json.load(jsonf)

       qr = qrcode.QRCode(version=1, box_size = 15, border = 5)
       data = jsonReader
       qr.add_data(data)
       qr.make(fit=True)
       img = qr.make_image(fill='black', back_color='white')
       img.save('Dieta.png')


jsonFilePath2 = filedialog.askopenfilename()
imageFilePath = filedialog.asksaveasfilename()

browseButton_CSV = tk.Button(text="     Importa JSON File     ", 
command=json_to_qrcode(jsonFilePath2, imageFilePath),
                          bg='green', fg='white', font=('helvetica', 12, 'bold'))
canvas1.create_window(150, 130, window=browseButton_CSV)

root.mainloop()
