Problem Statement:

Below relation is working on localhost but throwing error on Server. This seems like issue is with Doctrine/Inflector package.

CodePudding user response：

The problem is that the doctrine inflector method, maybe you need upgrade it otherwise other solution is upgrade your version of Laravel to at least 7.x.

Try to upgrade your version of your packages in your command line:

composer update

and then install the new doctrine/inflector:

composer require doctrine/inflector
