Using multi-proxy on pyinstaller gives an error

[AlexPaiva]

Without pyinstaller multi-proxy flag on a raw driver works fine, with pyinstaller it gives this error on any chrome opened except the first one:

File "selenium\webdriver\common\selenium_manager.py", line 137, in run
  File "json\__init__.py", line 346, in loads
  File "json\decoder.py", line 337, in decode
  File "json\decoder.py", line 355, in raw_decode
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

The above exception was the direct cause of the following exception:

Basically if I delete the downloaded_files folder and run pytest xdist with 1 thread with pyinstaller works fine, as soon as I open a thread with pytest xdist -n 2 or more than 2 it opens 1 browser fine and the rest give this error. If I don't delete the downloaded_files folder after it's creation it won't start any more browsers and give this error. If I delete it, it can open 1 browser fine the rest give the above error. I assume it's a simple path related issue?

Update: it's actually do to the ad_block_on=True flag not multi-proxy, my mistake. Threads with ad_block_on=True on pyinstaller don't start properly and give that error.

The ad_block_on=True is the old way of ad-blocking.
It's been made obsolete by the new CDP system: SeleniumBase/examples/test_cdp_ad_blocking.py

The old way has been kept for backwards-compatibility, but there won't be any more updates to it.
It isn't even configured for Manifest-V3 Chromium extensions, which are replacing Manifest-V2.

If using the old way gives you pyinstaller issues, then there's a simple solution: Don't use it.

Also, pyinstaller is an external program with its own rules and bugs. If using it changes default SeleniumBase behavior, then there's little that I can do about it.

Got it, was using it to test aswell. Pyinstaller is for frozen envs, compatibility for them usually is just a matter of path issues.

Thanks!
