I don't understand what could possibly go wrong I changed one line of code only.

Hey! It seems the code style is not according to PSR2

Hey.

if ($meta = $this->meta()->where('meta_key',$attribute)->value('meta_value')) {

Here's the code.Could you be more specific?
I still don't know what's wrong.

Here's the code.Could you be more specific?

As per PSR-2

Code MUST use 4 spaces for indenting, not tabs.

You've got a mix of spaces and tabs in your PR

Oh cool thanks for clarification.
I guess using the metas like this are not a good idea anyways.

My solution does make a lot of queries.
The main solution did make one query that got all the meta.

I did try caching on both and the results are still slow.

So I switched to other solutions like using with and with where condition to only get the metas that we need.

With only makes one query and it's the best for performance reasons also can be used on many rows and still so fast.
