The error message "PDF is not defined" usually occurs in JavaScript when you try to use a PDF-related function or object that is not available or has not been loaded.
For example, if you are trying to use the PDF.js library to display a PDF in a web page, you need to make sure that the library has been loaded and initialized correctly before you can use its functions to render the PDF.
You can check if the library has been loaded correctly by looking at the network tab in your browser's developer tools, or by checking the console for any error messages.
If you are still encountering the error, try checking the spelling and capitalization of the PDF-related function or object you are trying to use. It could also be possible that there is a syntax error in your code that is causing the issue.
