Problem in Php 8.1.5

[pranaycb]

I don't know why this error is comming. It was working fine in PHP 7.3 version. But when I update my PHP version to 8.1.5 then it's giving me this error. Any solution?

A PHP Error was encountered
Severity: 8192

Message: Return type of Symfony\Component\HttpFoundation\ParameterBag::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice

Sorry I was never test it with PHP 8.1.x, but from the errors above it tell that the errors comes from the symfony http-foundation package.

I will look at that for the compatibility.

Thanks for the report
