Vue3 is packaged and deployed to the service Cannot read property 'custom' of undefined
This is really a pit, I thought it was the fault of the code, I searched over and over again, deleted the code over and over again, deployed it to the server over and over again, searched for the problem one by one, and worked overtime until late at night, only to find out that it was a problem with the qs plug-in
Solution: Find a lower version of "qs": "^6.9.5"
pit!
pit!
