Unsupported browser: {scrub_url_credentials(browser)}. Suppo

Error message

Unsupported browser: {scrub_url_credentials(browser)}. Supported: {', '.join(SUPPORTED_BROWSERS)}

What it means

Raised by extract_all() in agent_reach/cookie_extract.py when the browser string (after .lower()) is not in SUPPORTED_BROWSERS = ('chrome', 'firefox', 'edge', 'brave', 'opera'). The value is scrubbed with scrub_url_credentials before being echoed, so embedded secrets never leak into the message.

Solutions

1. Use exactly one of: chrome, firefox, edge, brave, opera (case-insensitive)
2. Map generic names in your code: 'chromium' -> 'chrome', 'msedge' -> 'edge'
3. Check the message — it lists the full supported set

Example fix

# before
extract_all(browser='chromium', platform='bilibili')  # ValueError

# after
extract_all(browser='chrome', platform='bilibili')

SUPPORTED_BROWSERS = ('chrome', 'firefox', 'edge', 'brave', 'opera')
if browser.lower() not in SUPPORTED_BROWSERS:
    raise ValueError(f'unsupported browser {browser!r}')

def is_supported_browser(browser: str) -> bool:
    return browser.lower() in ('chrome', 'firefox', 'edge', 'brave', 'opera')

try:
    extract_all(browser=browser, platform=p)
except ValueError as e:
    if 'Unsupported browser' in str(e):
        browser = 'chrome'
    else:
        raise

When it happens

Trigger: Calling extract_all(browser='chromium', ...) or 'Safari', or a typo like 'Chrom' (lowercased to 'chrom' and rejected).

Common situations: Assuming any Chromium fork works; passing 'chromium' where 'chrome' is meant; case differences are tolerated by .lower() but name variants are not.
