Sujets

I am trying to create a new block, for the first time, using BlocklyArduino.

I can add the new category to the palette and the new block has the right colour and I can move it onto the canvas.

When I press the <Source> button I get the following error

TypeError: Cannot read property 'call' of undefined.

Can someone give me some guidance as to how I can narrow this error down?

Thanks for your help.
