large file throws error Uncaught (in promise) Error: Invalid argument passed to jsPDF.scale

[rutasa]

Everything was working just fine until I tried to add 87th element to the generated pdf file. At that point, it started throwing error Uncaught (in promise) Error: Invalid argument passed to jsPDF.scale.

My setup:

const doc = new jsPDF("landscape", "px");

const elements = document.getElementsByClassName("customChart"); 

await creatPdf({ doc, elements });

doc.save(`charts.pdf`);

are you find any solutions for this?

@rizkhal for me it was because the height of the image is being set to 0 during the conversion HTML element to canvas and then to base64, leading to the height being undefined during pdf.addImage method.

So including elements with a height of more than 0 works for me.
