Solved: Help - QR Code does not generate

Hi,

My QR codes have been working for the last year, however over the last couple days it does not generate anymore. I am using;

and i append the data onto the end of this using a variable as it changes depending on the batch number which is editable.

Below is the code;

This VarQrBatch is a text label which is generated when the batch info editable "text input" is changed.

Does anybody know what may be the cause for this not working?

It has stopped working in every instance i am using this API.
