PHP Fatal error: Uncaught Error: Class 'FPDF' not found in

I am working to implement the artkonekt/pdf-invoice project from GitHub.

I used the normal composer require konekt/pdf-invoice install method as specified in the readme.md file--and everything installed without any errors.

When I simply try to view the provided example file /vendor/konekt/pdf-invoice/examples/example1.php, the browser gives back an "HTTP ERROR 500" and the Apache2 error.log file includes the entry:

[Thu Sep 30 11:02:40.813756 2021] [php7:error] [pid 26112] [client 72.36.41.73:55343] PHP Fatal error:  Uncaught Error: Class 'FPDF' not found in /var/www/html/generate/vendor/konekt/pdf-invoice/src/Invoi
cePrinter.php:18\nStack trace:\n#0 /var/www/html/generate/vendor/konekt/pdf-invoice/examples/example1.php(5): include()\n#1 {main}\n  thrown in /var/www/html/generate/vendor/ko
nekt/pdf-invoice/src/InvoicePrinter.php on line 18

Other than the attribution credits at the top of InvoicePrinter.php, the next few lines are:

namespace Konekt\PdfInvoice;

use FPDF;

class InvoicePrinter extends FPDF
{

Line 18 is the class InvoicePrinter extends FPDF one.

The composer.json file contains:

{
    "require": {
        "konekt/pdf-invoice": "^1.10",
        "setasign/fpdf": "^1.8.4"
    }
}

and the setassign/fpdf directory is present and contains the fpdf.php file as one would expect.

Thus, how can the FPDF class be missing when it is both explicitly defined and verified as being present where composer expects?

I have tried running composer install && composer update && composer dump-autoload --optimize just to make sure...

Would someone point me in the right direction? I would have reported this as an issue in GitHub, but the repo owner has disabled issues. Thank you in advance for any assistance!
