PDFMake: Uncaught (in promise): Invalid image: Error: Unknown image format

I am getting the error when generating the PDF with base64 images using pdfmake in angular. In the content array sent to pdfmake. I see that the base64 images are converted into a format "$$pdfmake$${number} " and the other base64 images are still as base64. Not sure why the images are not rendered and why I am getting the error. The same code is working for low number of images, but when I give more number of images for the pdf it is throwing the error.

Error:

Uncaught (in promise): Invalid image: Error: Unknown image format. Images dictionary should contain dataURL entries (or local file paths in node.js)

pdfmake angular

it would be nice to see what code you've tried so far but if I had to guess, I'd say that your base64 encoded images aren't in the good format:

As seen in pdfmake's documentation, you can only use JPEG and PNG.
