How to get the path of a exe file in AWS layer?

I am trying to use wkhtmltopdf with a lambda. I create a zip file with the structure and make an layer.

wkhtmltopdf.zip

├───bin
├───fonts
│   └───dejavu
└───lib

where wkhtmltopdf.exe is in the bin folder. My code,

pdfconf = pdfkit.configuration(wkhtmltopdf=os.getenv('PATH')+"/wkhtmltopdf.exe")

The error message,

No wkhtmltopdf executable found: "/var/lang/bin:/usr/local/bin:/usr/bin/:/bin:/opt/bin/wkhtmltopdf.exe"

Thanks for your valuable time.

Solution

According to OP's comment, the correct path should be /opt/bin/wkhtmltopdf.exe.
