Spreadsheet API Problem


Hello i jope some one can Help me.
I want to work with the Cloudstich Spreadsheet

I make a free Accoubt and put all my data in the stheet that i need in my app.
Like on the thunkable videos on youtube i put ?dev=true after the widget name.
Now i want to load the Data from B2.
But when i test the app and press the button to load the data to the label i get each time an error.
Attemp to invoke virtual Method int.java.lang.intenger.intValue() on a null objekt referenz

I try everything to get the data into my app.
