Exit with code 1 due to network error: ContentNotFoundError

Solution 1

SOLUTION: This is for those with the error:

Exit with code 1 due to network error: ProtocolUnknownError

If you get an error when uploading an image/media, you have to upload that image to your own http server or hosting, for example in XAMPP. Put the complete link of the image in the html, example:

<img src='https://127.0.0.1/web/chart.jpg'>

In this way the images will be loaded well at the time of passing them to pdf. When creating the pdf, you can already delete the image from the hosting or remove the server.

Solution 2

This is happening when the renderer could not load a/some javascript/image/font file. After resolving missing resource, the issue was fixed.
