Can you share the PDF in question? We normally already have a fallback implemented:
FPDI/src/PdfParser/Filter/Flate.php
Lines 45 to 50 in 88a3aff
from fpdi.
With this PDF for example it was not working for me.

The file works without a problem and already the fallback I quoted before is used. I isolated the logic to this and all PHP versions work there, too.
What PHP version are you using? And what is the zlib version that is used? (see phpinfo() output).
from fpdi.
PHP 8.0.26
zlib 1.2.7
I think, I have found a possible problem for me.
You supress the errors with "@" before the gzuncompress and then the fallback will raised.
I have a custom Error Handler implemented, which prints the warning "Warning: gzuncompress(): data error" anyway.
So my script fails, because of this output there.
Think this solves the problem for me.

Ok, so you simply need to adjust your error handler to take care of the current error level:
function myErrorHandler($errno, $errstr, $errfile, $errline)
{
if (!(error_reporting() & $errno)) {
// This error code is not included in error_reporting, so let it fall
// through to the standard PHP error handler
return false;
}
