An internal curl error has occurred within the executor! Error Msg: Http invalid protocol

Most of the calls I make to my functions fails with this error. For example, when I open my app it will fetch 4 items from the database and for each item it will call a function passing their id and the function will only make a query to the database ($databases->getDocument('proj', 'db', 'id')) and a request to an external API using GuzzlePHP (takes less than 500ms when I make this APIrequest through postman). Appwrite fails almost all the time with the error above and sometimes with others like the ones below:

Failed to connect to appwrite-executor port 80 after 10243 ms: Couldn't connect to server with status code 0\nError Code: 0 or Operation timed out after 30001 milliseconds with 0 bytes received with status code 0\nError Code: 0

The errors above I see in the openruntimes-executor container. If I go to the logs of the container it creates to run the functions I only see Warning: foreach() argument must be of type array|object, null given in /usr/local/server/src/server.php on line 86

Is there any way I can see more detailed logs? I have no idea what's going on.
