**Silverstripe Version: silverstripe 4

Question:
Running into the following error when trying to run /dev/build?flush=1 for the first time.
I am using WAMP. Someone else created the project and I have cloned and am attempting to work on it as well:

[Emergency] Uncaught Error: Call to a member function obj() on null

GET /dev/build?flush=1

Line 180 in C:\wamp64\www\pilgrimage\vendor\silverstripe\framework\src\View\SSViewer_Scope.php

here is my .env

Do you have any more information about the error? There should have been a lot more in the stack trace than just that one line.

Are you running the same versions of PHP / MySQL as the person who built the project?

How did you install the code for the project? Did you use any composer commands?

Do you have any additional modules installed?

The error does suggest that it could be template related, so it may also be worth looking in the templates to see if there’s any unusual code in there.

I he was on 8.1 for PHP so I have now moved to that as well however for MYSQL he is on 5.7 and on my WAMP server its 8.2.0. However he explained it should work with MYSQL 5.6 and up ?

OK, so this needs to be sorted before you go any further. Silverstripe 4 isn’t PHP 8.2 compatible, so you’ll need to build it on PHP 8.1. In general, it’s important to run the same version of PHP in all your environments for a project, since composer will install some dependencies based on the version.

Now you’ve switched to 8.1, have you re-installed the composer packages?
