I have a workaround but kept running into issues. Feel free to troubleshoot further, but I think I'm just gonna look for alternatives to perplexity with how many problems keep appearing.

Some necessary dependencies:

pip install selenium undetected_chromedriver setuptools

In perplexityai\init.py:

from json import loads, dumps, JSONDecodeError
from selenium import webdriver
import undetected_chromedriver as uc
import re

Same file in Perplexity's class constructor. Replace the response = (... line with this code block

        driver = uc.Chrome()
        driver.get(f"https://www.perplexity.ai/socket.io/?EIO=4&transport=polling&t={self.t}")
        response = driver.page_source
        json_match = re.search(r'0(\{.*\})', response)
        if json_match:
            json_data = json_match.group(1)  # The JSON string we need
            try:
                parsed_data = loads(json_data)  # Parse JSON data
                sid = parsed_data["sid"]  # Access sid field
            except JSONDecodeError as e:
                print("Failed to parse JSON:", e)
        else:
            print("No JSON data found in response")
        driver.quit()

Basically it uses a headless browser to pass some security checks then filters the pulled html for the actual JSON with regex.
Again it gets around this issue but another one comes up when asserting a POST request.
Happy Troubleshooting :^)
