Hello @voducdat,

• It looks like you're encountering an error when running your Go code that involves generating a PDF using wkhtmltopdf. The error message "fork/exec /usr/local/bin/wkhtmltopdf: exec format error" suggests that there is an issue with the executable file for wkhtmltopdf.

• To fix this issue, you may want to check that wkhtmltopdf is installed correctly and that its executable file has the correct permissions. You may also want to ensure that you have the correct version of wkhtmltopdf installed and that it is compatible with your operating system. Additionally, you could try specifying the full path to the wkhtmltopdf executable file in your code to ensure that it is correctly referenced.

I hope this helps! Let us know if you have any further questions or concerns.

I just wrote a library with the help of gpt, which is much more efficient for simple HTML: https://github.com/html2any/layout. You can try it
