Deprecated Functionality: Function ReflectionType::__toString() is deprecated in /var/www/html/vendo

[starlyns]

I just unzipped a new template in a new M2 installation and after trying to upgrade with 

php bin/magento setup:upgrade  the upgrade stops with this warning 

Deprecated Functionality: Function ReflectionType::__toString() is deprecated in /var/www/html/vendor/zendframework/zend-code/src/Reflection/ParameterReflection.php on line 84

I am in a AWS ec2 installation.  

How can I fix this I find nothing online

Hello @starlyns 

Are you using php version 7.4?
Magento 2 is not compatible with PHP 7.4, try lowering the php version.

@starlyns you can try the soltution as suggested by @theMageComp.

If that doesn't work then go to the above mention line no. and Use getName() instead __toString() .

Thanks

Magento was working fine after the installation. I completed the installation and 

I just happened to unzip a template and after that, I started getting that error.

@starlyns please let me know your current version of php?
