Avilable memory exhausted in Google/Protobuf/Internal/Message.php on line 130

Your client library and Google Ads API versions:

• Client library version: v25.0.0
• Google Ads API version: V18

Your environment:

• The PHP version: 8.1.
• The name and version of the operating system: Linux 7ff3257dd078 6.10.14-linuxkit #1 SMP Thu Oct 24 19:28:55 UTC 2024 aarch64# - a docker image
• Whether the PHP Extension protobuf is used or not: NO, a Composer library is used.
• Whether the PHP Extension grpc is used or not: YES, 1.68.0, but the problem persists without it.
• The type of transport being used (grpc or rest): grpc

Description of the bug:
I switched to v18 version of the API. I updated the client version to v25 and updated all the calls i'm making. Most of the calls make it through and return data. Larger call that requests data from search_term_view reports a memory exhausted error.
I tried using search() - the memory error is returnd the moment i call the search function
I tried using searchStream() - the call goes through, and the memory error is returned the moment i try to call iterateAllElements() on the result of the call.
The error is: "Allowed memory size of 536870912 bytes exhausted (tried to allocate 20480 bytes) in /var/www/html/vendor/google/protobuf/src/Google/Protobuf/Internal/Message.php on line 130"
I made sure i'm using the latest version of the protobuf composer package, the version is v4.29.1
I know for a fact, that the call i'm trying to make is returning around 7k rows(i checked on google ads) AND it worked previously when the app was used.
I don't know if i can paginate the results of searchstream() - there's no documentation about that, or i couldn't find it.
I can't set the pageSize of search(), the option is deprecated, so i need to fetch the whole result.
I can set "LIMIT XXX" on the query itself, but then, if i understand correctly, there's no way to "get the next page" so to speak.
I removed every single thing that i could from a function that calls the API except for the call itself, and an empty foreach that iterates on the results, and it still reports a memory error.

Anything else we should know about your project / environment:
It worked around 2 years ago. I specifically checked to see if i had everything updated. I had the same problem sometime before (up to api v14 iirc) and decided to raise the memory limit to 512MB, but right now, for a 7k result set i'd have to raise it to 2G(it goes through then), which i cannot do.
I skimmed through some issues on here and the protobuf repo and none helped.
