Pdfmake: Cannot read property 'createPdf' of undefined

[HarshSaudagar]

I am not able to print my canvas. I am using html2canvas in conjunction with pdfmake. This is what the error logs:

Error canvas TypeError: Cannot read property 'createPdf' of undefined

Can you please let me know what is the issue ?

You probably do not include pdfmake library or call wrongly createPdf method.
