Thanks.
My code is compatible with 7.4. This code section which makes this troubles is from symfony. In bootstrap.php is on line 14 to 16 following statement:
if (\PHP_VERSION_ID >= 80000) {
return require __DIR__.'/bootstrap80.php';
}
Which calls the bootstrap80.php which contains the mentioned method.
I don’t want to change the library before publishing. What hint do you have for me that I can do the release?
